A 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.
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.
