- A cone is divided into two parts by drawing a plane through the mid point of its axis and parallel to its base. Compare the volume of two parts.
- A metallic right circular cone 20 cm high and whose vertical angle is 60° is cut into two parts at the middle of its height by a plane parallel to its base. If the frustum so obtained be drawn into a wire of diameter 1/16cm, find the length of the wire.
