cone
and the area of the curved surface equals π rl.
More generally, a cone is the surface consisting of the points of the lines, called generators, drawn through a fixed point V, the vertex, and the points of a fixed curve. The generators may be extended indefinitely in both directions to form a double cone. See also quadric cone.
