cone is a pyramid with a circular cross-section.

A cone has a round or base and a top that becomes narrower until it forms a point (vertex).

The volume of a cone is one-third the area of the base times the height.

Surface Area

The surface area of a cone is equal to the curved surface area plus the area of the base.

The height of a cone is the perpendicular measurement from the base to the top of the cone (vertex).

Slant height is the height along one face of the cone.


The total surface area of a cone is given by    π•r(r+s)
