The formula for the volume of a rectangular solid, V=Bh V = B h , can also be used to find the volume of a cylinder. For the rectangular solid, the area of the base, B , is the area of the rectangular base, length × width. For a cylinder, the area of the base, B , is the area of its circular base, πr2 π r 2 .

The formula for the lateral surface area of a cylinder is 2πrh, where r = radius and h = height. The formula for the lateral surface area of a sphere is the same as the formula for the surface area of a sphere, since it has no bases. Thus, the lateral surface area of a sphere is 4πr2, where r = radius.
