Man the Americans… everyone knows that π=-10
Think of the Loch Ness Monster and use tree fiddy and you’re much closer
Ah said MONSTAH!!
Calculator not allowed test probably
Even if so, the other factors are both 10. How hard can it be…
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.
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.
If the goal is to avoid calculations with decimal places, why not just leave Pi in the result?
I wish the 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
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?
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
This is how you develop trust issues.
Americans are more fat so they need bigger Pi to keep geometry in touch with reality.
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.
I’m American. I got 80% on my IQ test am I dumb? That’s a GPA of 3.0.
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
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.
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!
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.
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
My buddy in high school had it memorized it to 700+ digits. He was bored.
I’ll remember that, but she is four now…
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.
Von nichts kommt nichts. Also los.
I’m fine with 3, maybe 4, but 5???
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.
might also be to teach actually reading the instructions instead of blindly typing pi into the calculator
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)
100%, also how would I indicate to colleagues or successors when I used what value for pi? Clear diving is a thing for me.
Safety factors are both more explicit and self-documenting up to a certain point.
Factor of pi-safety
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…
