Just use 4 for pi
But it says π is 5
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 !!
Geology rocks
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
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.
This is in contrast with how pi is otherwise consistently expressed on the Disc, which is “three and a bit.”
Notably, Bloody Stupid Johnson is so skilled/inept that he actually does make pi equal to three within the machine… somehow… which breaks reality in a small amount of space inside it.
Apparently King David had this skill as well, since this is mentioned twice in the old testament:
1 Kings 7:23: And he made a molten sea, ten cubits from the one brim to the other: it was round all about, and his height was five cubits: and a line of thirty cubits did compass it round about.
Clearly π was equal to 3 in old testament times, but geometry got all screwy when Jesus died for our sines.
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!
It’s in a different language.
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.
I got my daughter to memorize 50 digits of pi when she was 11 or 12 by betting her $50 she couldn’t.
I’ll remember that, but she is four now…
Von nichts kommt nichts. Also los.
I’m goons gonna try it with my 7yo. I’ll report back if he gets anywhere. On the plus side $10 should be enough incentive.
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
My buddy in high school had it memorized it to 700+ digits. He was bored.
I’m fine with 3, maybe 4, but 5???
might also be to teach actually reading the instructions instead of blindly typing pi into the calculator

Round Up.
round
heh
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?
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.

I’m not the one making dumb generalizations. Fuck off with your stereotypes.
You’re literally a walking stereotype, incredible!
Well, stereotypes are lazy humor, and I’m lazy & my life is a joke - so you’ve got me there.
Fair enough
I’m American. I got 80% on my IQ test am I dumb? That’s a GPA of 3.0.
Manlet. Barely better than fatass.
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.
“Now this is a fucked up situation.”
Believe it or not, there is precedent for this.
Sick burn. Especially from a Belgian! Waddle waddle
3,140, uh, somethings? LOL, I started without realizing they defined pi as 5.
This is how you develop trust issues.
It went to far and Beck.
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
That’s because you were supposed to rhombusulate, not triangulate.
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.
I think that reason would make it “Technically Yes”, since False (pi = 5) implies False (cylinders exist) is (vacuously) True (“absurd premise”).
Yes. The 3d shape existence is not affected by changing pi values
Cause it’s just a (n-1)-dimensional ball extruded along the remaining axis, or do all 3d shapes exist on (nearly) all 3d metrics?
Mostly because the actual pi values can vary in between non/euclidean geometries. Within extremely strong gravitational fields, spacetime becomes highly non euclidean, affecting the C/d ratio of an actual circle, so I’d wager this would affect pi as well
If the goal is to avoid calculations with decimal places, why not just leave Pi in the result?
That would work too.
I wish the would have used 22/7 for pi and 7 for the radius or height
The teacher is obviously a fat fuck that dreams of more pi.
Think of the Loch Ness Monster and use tree fiddy and you’re much closer
Ah said MONSTAH!!
Ah yes, all those imperial units…
Ha Ha, non-Euclidian geometry go brr. :)
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
Every engineer knows pi is 3 🤦♂️
+/-0.2
e=π=3=√g=√10=c*10^-8
