Volume of a Cylinder
Date: 7/30/96 at 15:50:29 From: Anonymous Subject: Volume of a Cylinder I need help with this problem. Here goes: A cylindrical storage tank has a diameter of 6m and a height of 5m. What is the volume of the storage tank?? I know this is a fairly simple problem, but I've forgotten the formula for the volume of a cylinder. Could you help by sending me this formula, please? Thanks for your time, Lindsay

The area of the base is pi times r^2, where r is the radius. So the complete "formula" would be V = (pi)r^2 x h where h is the height. The answer to your problem would be V = pi 3^2 x 5 = 45 pi cubic meters or approximately 141.37155 cubic meters. -Doctor Robert, The Math Forum Check out our web site! http://mathforum.org/dr.math/
