I'll post a few problems (pic related)

Where'd the pi go?

If you can't solve this yourself, you're guaranteed to fail every math related class you ever take in the future. Sup Forums solving one homework question for you will not help.

Put the numbers in, start with 3 and replace t with it (for your p function), then do 3t or 3*3 which gets you 9, next put the result 9 you get and put it into the V function, 4/3 * pi * (9 squared) which gets 12 pi

Well, if you plug in the 3 for t you get v(9), so then you'd get (4/3)((pi9)^2), right?

but you cube the 9 before multiplying by pi, the final answer is like 3000 something i think

well we gave 2 explanations so if you still don’t get it, please explain why.

I figured out the first one Sup Forums,what about this one?can someone give me a brief explanation?

You're evaluating V(9), but you guys seem to be reducing the cubed to a squared for some unknown reason. Simplify 4/3*pi*9^3, which is much bigger than 12pi.

you just got to plug the numbers in, for example for function r, start by pluging 0 into function q and then taking that result and pluging it into function p.

Wrong.

That is an approximation, the actual answer needs to be expressed im terms of pi.

Literally just plug all the numbers in

p(t) = V(3t), so p(3) = V(3*3)

V(r) = (4/3)pi*r^3, so V(9) = (4/3)pi*(9)^3

Plug (4/3)*pi*9^3 into a calculator and win

dude, look st the chart, for 0 snd q it says 4 so do 4 now for p, in the chart at 4 p it says 1, so the answers q...

Sup Forums seems to be getting younger every year

People used to ask for calculus or physics help

Now they're asking for basic algebra

What are you, 14? Go to bed, kid
