They probably say the same thing about us.

I thought we were past the Jeans thing… But here you are, pulling us back in.

I would be a smartass and leave Pi as a factor throughout and in the answer. I’m used to doing that in Calculus anyways.

V = πr^2^h

V = π⋅10^2^⋅10

V = π⋅100⋅10

V = π1000

BONUS SOLUTION:

V =∫0^10^ A⋅h dh

A = ∫0^10^ 2πr dr

V= ∫0^10^ ∫0^10^ h⋅2πr dr dh

h is a constant for A’s integral so we can safely move it into V’s integral

V= ∫0^10^ h⋅∫0^10^ 2πr dr dh

π is a constant so we can safely remove it from A’s integral

A = π⋅∫0^10^ 2r dr

A = π⋅[r^2^]0^10^

A = π⋅( [10^2^] - [0^2^] )

A = π10^2^

A = π100

V = ∫0^10^ h⋅π100 dh

π100 is a constant so we can safely remove it from V’s integral

V = π100⋅∫0^10^ h dh

V = π100⋅[h]0^10^

V = π100⋅([10] - [0])

V = π100⋅10

V = π1000

It goes a lot deeper but I’m not bored enough for that, yet.

EDIT: Hang on. I’m wrong with that height integral. Can somebody help remind me?

If you really wanted to be through you’d start at a point, integrate out along dr for a line, then integrate in a circle through dtheta to derive the area before doing the rest

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

Agrivar ,

Here’s a little LPT for you: you can be correct without being an obnoxious douchebag about it.

FanBlade ,

Your message reads kinda douchey.

Yeah, “symbol thingy” is setting me off rn.
The only thing that can help me is filing my taxes incorrectly.

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.

    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.

    gimpchrist , (edited )
    @gimpchrist@lemmy.world avatar

    I’m dyscalculic… I’m allowed to have an opinion on it this is how my brain works.

    Also if we can’t say that pi is just a little symbol thingy then I guess we better stop using fucking exclamation marks everywhere

    petrol_sniff_king , (edited )

    Mathematically, no, it does not. We make up the definitions. If you wanted to see what the consequences of a, I don’t know, 5-dimensional universe with Pi set to 5.65 were, you can do that. These are scribbles on pages, there is literally nothing stopping you.

    Academically, what’s stopping you is whether these calculations are useful. The only problem I see here is that it’s kind of misleading to imply to someone that Pi is something it conventionally isn’t. But even then, I think I’d respect the mathematician who could recognize Pi as a symbolic name for, usually, one particular transcendental constant a little bit more than one who refused to even entertain the idea. Like, imagination is important to mathematics, too.

    And to be clear, “let Pi = 3.14” is also incorrect. It is closer than 5, but it is still infinitely wrong.

    [edit] And also, I was imagining this question was for a younger audience. Reading it again, I’m not going to pretend I know what’s going on up there.

    Sometimes you’ve just really got to let it out, and you need to make time to do it. Really makes ya sad that people break down to that point and can’t just take a minute for a hug.
