A right circular cylinder with radius r and height h.

A cylinder (from Greek κύλινδρος – kulindros, "roller, tumbler"<ref>κύλινδρος, Henry George Liddell, Robert Scott, A Greek-English Lexicon, on Perseus</ref>) is one of the most basic curvilinear geometric shapes, the surface formed by the points at a fixed distance from a given straight line, the axis of the cylinder. The solid enclosed by this surface and by two planes perpendicular to the axis is also called a cylinder. The surface area and the volume of a cylinder have been known since deep antiquity.
