A cone is a special case of the pyramid; it's a pyramid with a circular base.
- Given the radius of the base
and the slant height of the cone 
, the volume of the cone is 
.
and the 
, the volume of the cone is 
.The surface area of a cone where r is the radius and h is the slant height is \pi(r^2)+\pi(r)(h). This article is a stub. Help us out by expanding it.
