A solid with a circular base and a curved surface tapering to a point.
For a cone or pyramid, volume uses the perpendicular height; surface area usually requires a slant height or the perpendicular height of each triangular face.

A cone also narrows to a point, but it has a circular base and a curved surface rather than triangular faces. A cone is not a pyramid because its base is not a polygon and its joining surface is curved.
