The definition of a cone may be extended to higher dimensions; see convex cone. In this case, one says that a convex set C in the real vector space R is a cone (with apex at the origin) if for every vector x in C and every nonnegative real number a, the vector ax is in C. In this context, the analogues of circular cones … See more A cone is a three-dimensional geometric shape that tapers smoothly from a flat base (frequently, though not necessarily, circular) to a point called the apex or vertex. A cone is formed by a set of line segments, half-lines See more In projective geometry, a cylinder is simply a cone whose apex is at infinity. Intuitively, if one keeps the base fixed and takes the limit as the apex goes to infinity, one obtains a cylinder, … See more • Weisstein, Eric W. "Cone". MathWorld. • Weisstein, Eric W.
