This is how the wealthy calculate their tax exemptions.
To be Devil’s Advocate:
Given that the rest written in Comic Sans, it may be an early elementary school exercise, aimed at teaching kids to do multiplications. In this case, it’s tolerable and/or defensible to find a simplification for pi.That said, making pi equal to 3 would have been more accurate for that…
Unless the kid is even slightly above average and finds the idea that pi equaling 5 confusing.
…if they’re above average, I think they’ll figure out the explicitly defined variable. I think the instructor is trying to make sure this problem doesn’t require a calculator and figured defining pi as 5 makes it clear that you can treat it as a whole number. 3 would be more accurate and just as easy, but meh idk that this is that great of a blunder.
You can be a smart kid and not realize that adults are lying.
I remember the Peas and the Punnett Square. Sure, mendelian genetics explains pea plant colors, but doesn’t explain dog fur colors. Just providing a footnote that more completed genetics exists would have been nice.
Or it’s from an ME. They seldom can remember the rounded value of Pi, but they’re pretty sure it’s somewhere between 3 and 4. But you probably should use 5 just to be safe…
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.
Unless I fucked up.
π = 5 for very small values of r.
Ah, Indiana math.
New New math
Idk, if you want to test people on how they understand formulae and order of operations without letting them just punch it into a calculator. The actual math isn’t hard, but if you don’t get substituting values into an equation then it’s not trivial
That just means the curvature of spacetime is negative.
Nobody knows how to think like a dyscalculic at all haha… it’s just a little symbol thingy… it doesn’t have to be pi. Just like X is a little symbol thingy… the x is now just kind of a table right now… it’s just a little symbol thingy and it means five it’s not that difficult. Lmao
Here’s a little LPT for you: you can be correct without being an obnoxious douchebag about it.
Yes it does have to be pi because that’s the formula for the volume of a cylinder. If you take a simple, cylindrical glass or container and measure it and apply the formula with pi, you’ll see that you’ll get the correct volume of the container. If you just want your kids to calculate a random x that’s 5* 10 *10 *10 just tell them to do that, don’t give them a made up formula, it’s not that difficult.
None of what you said made any sense to me I still see that little thingy as a symbol and not as a representation of Pi I’m sorry too fucking bad you math nerd. The representation of Pi is the symbols 3.14 not a weird square symbol.
Well, let me put it another way. You don’t need to have an opinion on everything. It’s okay to not understand something and not have an opinion on it.
I’m dyscalculic… I’m allowed to have an opinion on it this is how my brain works
Numbers are symbolic, I’d say it’s not a bad piece of homework 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.
Reading that comment was a wild ride! It started off innocuous enough, but really went off the rails FAST!
Makes me miss the days of 22/7.
Nother one of them “uncertified teachers” huh
pi was mutable all along
My favorite is when doing Order of Magnitude estimations, you are supposed to let pi = 1
…in spacetime with high curvature?
