A solid wooden cone has been supported by a string inside water as shown in the figure. The radius of the circular base of the cone is R and the volume of the cone is v. In equilibrium the base of the cone is at a depth H below the water surface. Density of wood is d( ltrho , density of water). (a) Find tension in the string. (b) Find the force applied by the water on the slant surface of the coone. take atmospheric pressure to be p_(0) .

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 solid sphere of radius r melted and recast into the shape of a solid cone of height r, then radius of the base of the cone is (of equal volume)

If the base radius and height of a right circular cone are r and h respectively, then the volume of the cone is

If a sphere of radius 2r has the same volume as that of a cone with circular base of radius r , then find the height of the cone.

If a sphere of radius 2r has the same volume as that of a cone with circular base of radius r , then find the height of the cone.

The radius of the base of a solid right circular cone is 8 cm and its height is 15 cm. The total surface area of the cone is:
