From a given solid cone of height H, another inverted cone is carved whose height is h such that its volume is maximum. Then the ratio `H/h` is

The radius of base of a cone is r and height is h. Find its volume.

The radius of base of a cone is r and height is h. Find its volume.

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-

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

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

From a solid cylinder whose height is 2.4 cm and the diameter 1.4 cm, a cone of the same height and same diameter is carved out. Find the volume of the remaining solid to the nearest cm^(3) .

From a uniform solid cone of base radius R and height H, a symmetric cone of the base radius (R)/(2) is removed as shown. Then the centre of mass is shifted by H/n. Find the value of of n.

From a uniform solid cone of base radius R and height H, a symmetric cone of the base radius (R)/(2) is removed as shown. Then the centre of mass is shifted by H/n. Find the value of of n.

If a sphere and a cone oh height 'h' have same radius and same volume , then find ratio of 'r' to 'h':
