A cone made of paper has height 3h and vertical angle 2 alpha It contains two other cones of height 2h and h and vertical angles 4 alpha and 6 alpha respectively.Find the ratio of the two volumes in between the cones.

The vertex angle of a cone is 60^(@) . Find the ratio of diameter with the height of the cone.

Find the cylinder of maximum volume which can be inscribed in a cone of height h and semivertical angle alpha .

The volume of the greatest cylinder which can be inscribed in a cone of height h and semi- vertical angle alpha is

If h be the height and alpha the semi vertical angle of a right -circular cone, the its volume is given by

A cone of semi vertical angle of alpha is inscribed in a sphere of radius 2 cm. the height of the cone is

A cone of radius r сm and height h cm is divided into two parts by drawing a plane through the middle point of its height and parallel to the base. What is the ratio of the volume of the original cone to the volume of the smaller cone?
