?????

Answer 3

I don't do math sorry :( I'm doing summer school for math right now too lol.

Answer 4

Do you know the formula for finding the volume of a cylinder?

Answer 5

lol- sorry! @JimmyC This Geometry is kicking my butt =)

Answer 6

V=PI*h*r^2

Answer 7

Correct. Now plug that in.

Answer 8

Btw, what does x represent?

Answer 9

I have no idea how the x fits in

Answer 10

I'm guessing that x represent pi. So ignore pi for now.
What does 3^2 * 6 give you?

Answer 11

when I plug it in, I get 169.56

Answer 12

54

Answer 13

And I'm guessing since x represent pi, C should be your answer.

Answer 14

Why would they leave out the PI for x if they teach us the formula with using PI???? It's like deliberately confusing us >:-0

Answer 15

Thank you for helping me @GoldPhenoix

Answer 16

Don't ask me, I'm not the teacher.
But that's the only way I can think of.
There's no possible solution for the other answer choices.

Answer 17

I wasn't really asking. I was venting. I'm sorry.

Answer 18

No need to be sorry. :)

Answer 19

It just makes me a little angry that I study the formulas and learn the rules, only to throw in X instead of the formula! ;-)
