The volume of a cylinder of radius r and height h is given by V = π r 2 h. Then the height, in terms of the radius and volume, is given by:

Dec 20, 2014 - The volume V of a right circular cylinder of height h and radius r is V=pr^2h. If the height is twice the radius, express the volume V as a function of r ... Hi Tammie,. OK so we have the volume formula. V = (pi) r2h. and we know that h = 2r. so we can replace h with 2r and we get. V = (pi) r2 (2r). V=2 (pi) r3.
