A cylinder is a solid generated by rotating a rectangle about one of its edges. A cylinder may also refer to the surface of such a solid. A cylinder may also be thought of as the solid bounded by two parallel planes and the set of all points equidistant from a line perpendicular to both planes. Thus, a cylinder has two circular flat surfaces--think of a can of soup. Typically, to solve for surface are or volume of a cylinder, the radius of the circular faces and the height of the cylinder are involved.
