# Thread: volume of a cylinder

1. ## volume of a cylinder

Ive figured out most of the problem but im stuck at this point. Can anyone help me complete this?

1/3(pi) * (sqrt 20-x/2(pi) )^2 * (sqrt 80(pi)x-x^2)/2(pi). Ive used the formula where V= 1/3 (pi)r^2h. Thanks.

2. What is required for the "completion"? What are you needing to do?

Thank you!
