Answer 4

Well the volume of a cylinder is \[\pi * r ^{2} * h\]

Answer 5

sorry open study is being annoying

Answer 6

13*12 152

Answer 7

By any chance, do those answer choices have a "pi" in them?

Answer 8

yes

Answer 9

156 pi m3 all of them

Answer 10

Well then it's not A. You have to do pi * r^2 * h (which is 12^2 * 13 * pi)

Answer 11

so then C

Answer 12

I agree with comupter

Answer 13

so instead of guessing

look at the drawing

what is r?
What is r^2 (r * r)?
What is h?

Use the formula given above

Answer 14

i keep messing up

Answer 15

i dont get it

Answer 16

it is a simple multiplication

pi * r *r * h

put the values for that into your calculator.

If you keep messing up ,then practice until you don't

Answer 17

Well, as @MrNood said, you have to identify the parts of the cylinder and then use the formula. Here is a diagram for the parts of a cylinder.
