-In mathematics, a '''right circular cone''' is a three dimensional object formed by rotating two intersecting [[line]]s about the line which [[bisect]]s them.
-The intersection of a plane with this object forms an important set of two dimensional functions, called the [[conic section]]s.
-Cones in general do not have to be "right" or "circular", and may be truncated, i.e., not extend to infinity.  A familiar example of a (doubly) truncated cone is a basketball net.
-The volume of a cone is equal to the product of the base, height, and one third.
