Answer 2

Compare the two volume formulas:
\[V _{cylinder}=\pi r^2h\]
\[V _{cone}=\frac{1}{3}\pi r^2h\]

Answer 3

I don't know how to find the radius or the height

Answer 4

If the volume of the cone is exactly 1/3 the volume of the cylinder, what should you do to the volume of the cone to get the volume of the cylinder?

Answer 5

Multiply it by 3?

Answer 6

Very good!!!

Answer 7

Do that and you will have your answer.

Answer 8

So multiply 15 by 3?

Answer 9

That's what you said.

Answer 10

ok so it would be 45 then, right?

Answer 11

yep

Answer 12

ok thx that was easier than I thought.
