The answer is substantially different though. 3141 units (rounded correctly) vs 5000. That’s a significant margin that even working it out in your head is not forgiving enough to cover.
I think you’re overthinking it. The first thing you’re told when you learn algebra is that a letter represents a number and you can say “let a equal (number), b equal (number)…” so you can let pi equal whatever you want for the purposes of one simple problem.
Except pi isn’t a variable. It is a known value that we refer to as pi for convenience, and pi is a fundamental aspect of how a circle is. Saying “let pi equal 5” is all fine and well but is physically impossible, you will not be determining the volume of a cylinder if you let pi equal 5, because the ratio of a circle does not equal 5, it equals 3.14
But I suppose part of solving a maths problem is staying within the confines of the question and listening to instructions, so if someone says “using pi equals 5”, I’d just use pi equals five and take my point with grace.
Well, if we want to be pedantic, they never said that h is the height and r is the radius of the base circle. They could be just random numbers.
Also, since we never calculate with all the digits of pi, it is not any less weird to round to the nearest 5 and say that it’s 5, than to the nearest 0.01 and saying it’s 3.14. It just has a higher amount of rounding error.
I think it’s actually a very interesting question. Pi does not equal 5 in our universe, but perhaps we can think of a meaningful universe where it does? Perhaps some mathematicians/physicists can chime in?
Or 10, whatever. The precise value is only relevant when measuring the curve of space, and they’ll still disagree with mathematicians on most of the digits.
Kind of curious how you got that value. I think the ratio of circumference to diameter (“pi”) is actually smaller in spherical geometry, in the most extreme case (the equator) it’s just 1. You could say “pi = 5” for circles of a specific radius in hyperbolic geometry, I guess.
my mistake was using the sum of angles in a triangle which was kinda dum but whatever . I also tried calculating via the circumstance of a circle placed at a pole where π was 20x smaller for the case I was using but its not linear so I looked deeper which was a big mistake .
BTW the ratio of circumstance to radius for a circle which is also an equator of the space is ¼ not 1 (r=½π₀ , C=2π₀) .
The math doesn’t care, and what you’re on about only really matters if the units don’t start as all the same or if you start converting between things.
Numbers are symbolic, I’d say it’s not a bad piece of writing to supplement a lesson that numbers are to be respected but ALSO to always know that they mean nothing without context.
We can appreciate the beauty of infinity in memorizing pi, but the reality we live in demands actions of whatever the fuck it is we redefine volition, will, or passion to.
I think people can be so much more, but my idea of more is tainted by the values I have. Not everyone would agree with the idea that we all deserve to live.
Survival of the fittest, they support indirectly. With actions that include the advent of modern advertising. The CIA(?) experiment on attention, catalyzed by the creation of lsd in the knowledge-obtaining-goal of understanding the mechanics of attention, were directly related to the patriot act.
I’m not claiming anything other than the fact that our “leaders,” have used their knowledge of attention spans to sway the, “masses.” The rest of us.
How do you think of the, “rest of us?”
I hope you teach your children that, and that math is the beauty we’ve come to understand in our millennia of evolutionary timescales, of fucking struggle.
You have within you, much.
Do not waste the years of before, do something to help. Not your country, but your reality. The outside. You’re something. Not “nothing but a part of.” There’s so much in the word, “just.”
That’s all I have to say. Just that. Not much. Just a tiny little wall. Sorry. I write, and I rant, and I let go. Please don’t ban me. I matter and I’m not hateful. I’m sorry.
I truly wonder what sprouted this comment. We’re all taking about how this one teacher butchered math by rounding π completely incorrect and you’re posting this half-rambling, idk if medicaments-induced, pseudo intellectual crap. This has 0 to do with it, go to some DMT board.
