A cylinder has a radius of 5 in. If the volume of the cylinder is 250ƒà in.3, what is the height of the cylinder? [Hint: The volume of a cylinder is given by V = ƒàr2h.] 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 (ƒà) 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
