A cone is a shape formed by using a set of line segments or the lines which connects a common point, called the apex or vertex, to all the points of a circular base (which does\u00a0not\u00a0contain the apex). The distance from the vertex of the cone to the base is the height of the cone. The circular base has measured value of radius.
