A cone is a solid in which the base is bounded by a simple closed curve and the curved surface tapers into a point called the vertex, which is opposite the base. If the base is circular, the cone is known as a circular cone. The figure below shows some examples of cones with different bases.
The perpendicular height or simply the height of a cone is the perpendicular distance from the vertex to the base of the cone. The slant height of a right circular cone is the distance from the vertex to the circumference of the base.
