Has the imperial system gone to far?

Ha Ha, non-Euclidian geometry go brr. :)

Bye, bye, miss American PI.
- Maybe Vader some day later, but now it's just about prime.

What kind of problem gives you the formula and all variable to replace? At this point, why not just write 5•10²•10=?
- Intro to algebra type stuff to make sure you understand the concept of variables in the first place
  
  Even then, I would want them to leave π in the problem itself. That would be much better for this exercise - teaching that you report “exact” values with π still in them.
  Eg, if I rewrote this problem, I would expect an answer of 1000π.
  
  Pi= 5 in this teachers reality. Circles must look wonky.
- Cause reading comprehension is part of the test. Lots of kids will be able to solve that equation, but there's a bunch who can't understand it if it's presented this way.
  Honestly here they should have done "round pi to two decimal places" or smth.
- One written in Comic fucking Sans

This was written by an engineer. They rounded up to 5 for the safety factor.

It's official, the observable universe is ~3 times larger!

Man the Americans... everyone knows that π=-10
- Nah, π = 3.2.
  
  the Speaker accepted another member's recommendation to refer the bill to the Committee on Swamplands, where the bill could "find a deserved grave"
  Lmao
  
  What in the idiocracy

It went to far and Beck.

Americans are more fat so they need bigger Pi to keep geometry in touch with reality.
- I remember when Pi was monetized, that sounds like Pi Common, only $9.99/mo for 0 significant digits.
- Ah yes. I have heard about that.
  American Pi.
  
  Believe it or not, there is precedent for this.
  
  "Now this is a fucked up situation."
- Round Up.
  
  round
  heh
- Sick burn. Especially from a Belgian! Waddle waddle
- I’m an American. I weigh about 140 lbs (63.5 kg). I’m about 5.75 ft (1.75 m) tall. Am I fat?
  
  Fat? No, but dumb enough to understand my phrase as "each and every without a single exception". Dumb as an American.
  
  Yes, you should lose 100lbs. Just look at people who were forced on a diet. They were just bones because they had nothing to eat but flour and water. You got to go for the emaciated look.
  
  Manlet. Barely better than fatass.

Assigning a value of 5 to pi, although ludicrous IRL, doesn't affect the problem. Plug the values into the equation and it will still give an answer that's correct in context.
- For the benefit of doubt, maybe the test is from an alternate dimension that doesn't use euclidean space.
  
  Possible. I mean, electricity could actually be run by ghosts, but there's no need for fanciful explanations when a mundane one is right there.
  
  I've been there, I think, but it was really difficult to triangulate my location and confirm
- If the goal is to avoid calculations with decimal places, why not just leave Pi in the result?
  
  That would work too.
- I wish they would have used 22/7 for pi and 7 for the radius or height
- Do cylinders even exist in metrics where pi = 5 ?
  
  Technically no, because pi equals pi not 5. But you can approximate its value as 3 or 5 or whatever you want, knowing it's not exact and that your result will only be an approximation. I mean you could also ask how long light takes to reach us from Alpha Centauri if the speed of light is 1000 mph. It's not, but if you make that a condition of the problem you can do the calculation just fine.
  
  Yes. The 3d shape existence is not affected by changing pi values

Calculator not allowed test probably
- 3.14 would be easy enough to solve this one. r^2*h resolves to 1000, so V would be 3140.
- Even if so, the other factors are both 10. How hard can it be...
- I didn't get to use a calculator IN CLASS until late in my bachelor studies — forget about using them for tests. In a world with Chatgpt we need to teach in a more sterile environment or standards are going to swing into the ditch. My friend who is a grade school teacher has told me some stories that would make your ears bleed.

It’s clearly just saying that the surfaces on which the ends of the cylinder lie are metric spaces with distances defined using Chebyshev or Taxicab metrics based on pentagonal tilings of the parabolic plane so the ratio of a circle’s circumference to diameter is 5.
Since it’s a cylinder we assume the vertical dimension is Euclidean and voila the math checks out geometrically.
- Whoa, amazing!
  Astrology is so cool
  
  You know what's even cooler?
  G E O L O G Y !!

It's probably trying to teach kids algebra without using decimals. But it does look messed up. Everyone knows at least 3.14, except kids I guess
- My dad told me a rhyme to memorize like 15 digits of pi before I knew what pi is at like eight years old I'm guestimating. I remember it ever since.
  
  ... Yet refuses to share it with the world!
- I got my daughter to memorize 50 digits of pi when she was 11 or 12 by betting her $50 she couldn’t.
  
  My 7-year-old got obsessed and did it from a YouTube video to 100 places because he was bored.
  He also knows base 2 to 65536
  
  I'll remember that, but she is four now....
- I'm fine with 3, maybe 4, but 5????
- I don't understand. Aren't fractions better than decimals for algerba?
  Like 22/7 is better than 3.14 when it comes to pi for example.
  We always got taught to do everything as fractions and then convert to units at the last possible moment to reduce errors in rounding.
  
  Kiddos would need to know how to divide for that though. I'm just trying to come up with a reason for it lol.
- Everyone knows at least 3.14
  And biblical authors.
  
  In Terry Pratchett's wonderfully witty Discworld novel, Going Postal, the topic of pi comes up in a rather humorous and characteristically Pratchettian way.
  The newly appointed Postmaster General, Moist von Lipwig, encounters a rather eccentric inventor named Bloody Stupid Johnson. Bloody Stupid Johnson is known for his, well, stupidly brilliant inventions. One of these inventions is a new kind of postal sorting engine.
  When discussing the design of a wheel for this engine, Bloody Stupid Johnson proudly states that he designed it so that pi is exactly three.
- might also be to teach actually reading the instructions instead of blindly typing pi into the calculator

Think of the Loch Ness Monster and use tree fiddy and you're much closer
- Ah said MONSTAH!!

This is how you develop trust issues.

This question was written by an engineer
- Nice try, physicists.
- There’s good reasons they engineers over calculate, because they know things break, that people don’t do regular maintenance and that people will over stress the object. So engineers have to account for things like this when designing an object or a device so they don’t fail prematurely.
  
  Engineer here, I always just use pi and a "safety factor" multiplier. Extra material is expensive, and I want the cheapest part (like a screw) to fail first. We don't just oversimplify pi because half the time it'll make your design weaker.
  (If I just got whooshed I apologize)
  
  Factor of pi-safety
  
  I'm familiar
  It's funny because engineers are known for making simplifications like this, not because the simplification is problematic

In America, numbers are just bigger.
- Bigger numbers are better numbers!!!!! The best in the world!!!!!!1!11!!!11!

Every engineer knows pi is 3 🤦‍♂️
- e=π=3=√g=√10=c*10^-8
- +/-0.2

Ah yes, all those imperial units...

3,140, uh, somethings? LOL, I started without realizing they defined pi as 5.

Just round up to the closest multiple of 5.

In combat conditions Pi can reach 4 and E can reach 3. Maul halten und weiter dienen, all that.
OK. I might be thinking too much into this, but the metric system is good for practical use, but bad for didactic purposes. Some things which could use understanding are "automated" with the metric system.
So making Pi a variable is ... fine. Maybe it's some different geometry where it is.

Just use 4 for pi
- But it says π is 5

10 cubits with a circumference of 30 cubits, yadda yadda yadda
edit: oh holy shit I hadn't thought about this kerfuffle for 25 years but when I made this comment I went looking on the "internet" and holy shit the apology I found is insane. Absolutely in.sane.
Really, go look at the apologists trying to say that atheists don't know what they are talking about, that the measurements aren't precise, that there is a 4 inch rim that makes up for the difference. Just. Wow. Fucking WOW.
Any religious fucker that wants to @ me, bring it to my DMs. If you defend this bullshit about 10/30 cubits fucking bring it.
- Jesse what the fuck are you talking about
  
  Shh, the adults are talking.

The teacher is obviously a fat fuck that dreams of more pi.

AI?
- This image long predates AI.
  
  That classifies it as real stupidity :)
