A cone is circumscribed about a sphere of radius R. The volume of the cone is minimum if its height is: (A) 3R (B) 4R (C) 5R (D) `2sqrt(2)R`

A cone of height h is inscribed in a sphere of radius R , if the volume of the inscribed cone is maximum, then the value of h : R will be-

The radius of a circular cone is R and its height is H. The volume of cone is :

Height of greatest cone inscribed in a sphere of radius r is

Height of a cone,inscribed in a sphere of radius r, having greatest curved surface is

Derive the formula for the volume of right circular cone with radius r and height h.

Prove that the cone,circumscribing a sphere of radius r, has the minimum volume if its altitude is 4r and its semivertical angle is sin^(-1)((1)/(3))

Prove that the cone,circumscribing a sphere of radius r, has the minimum volume if its altitude is 4r and its semi vertical angle is sin^(-1)((1)/(3))

Write the formula to find and volume of a cone with radius 'r' and height 'h'.
