A metallic regent circular cone 30 cm high and whose vertical angle is 60° is cut into two part 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 ½ cm , Find the length of a wire?

A solid 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 1/12 cm, find the length of the wire.

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 1/16 cm, find the length of the wire.

A metallic right circular cone 20cm 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 1/16 cm find the length of the wire.

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/(16)c m find the length of the wire.
