Axis the fixed VO is called the axis of the cone.

Vertex the fixed point V is called the vertex of the cone.

Axis the line segment joining the centres of two bases is called the axis of the cylinder.

Let V be the volume of inverted cone with vertex at origin and the axis of the cone is along positive y axis. The cone is filled with water up to half of its height. The volume of water is

A right circular cone is sliced into a smaller cone and a frustum of a cone by a plane perpendicular to its axis. The volume of the smaller cone and the frustum of the cone are in the ratio 64 : 61. Then their curved surface areas are in the ratio
