Homework Help: mat 116/algebra

Posted by Dee on Sunday, May 13, 2007 at 10:28pm.

A cylinder has a radius of 5 in. If the volume of the cylinder is 250 in.3, what is the height of the cylinder? [Hint: The volume of a cylinder is given by V = r2h.] I think I wrote it wrong the first time.



The volume of a cylinder is pi r^2 h.
Your computer seems to be typing different symbols () for pi. If you meant to state that the volume of the cylinder is
250 pi in^3, then the height is
h = V /(pi r^2) = 250 pi/25 pi = 10 inches
