If radius is 2 cm then find the volume of a Ball.

A hemispherical bowl is made up of stone whose thickness is 3 cm. If the outer radius is 14 cm, find the volume of the bowl.

If the radius of the hemisphere is 21 cm, then find its volume.

If radius of circle 7/2 cm then find perimeter of quadrant.

The sphere is of radius 2.1 cm then its volume is ………. cm^(3).

A cylindrical tub of radius 5 cm and length 9.8 cm is full of water. A solid in the form of right circular cone mounted on a hemisphere is immersed into the tub. The radius of the hemisphere is 3.5 cm and height of cone outside the hemisphere is 5 cm. Find the volume of water left in the tub. " "("Take "pi=22/7)

If the volume of a spherical ball is increasing at the rate of 4pi cc/sec, then the rate of increases of its radius (in cm/sec), when the volume is 288pi cc.

In the adjacent figure, the height of a solid cylinder is 10 cm and diameter is 7 cm. Two equal conical holes of radius 3 cm and height 4 cm are cut off as shown in the figure. Find the volume of the remaining solid.

If there is an error 0.01 cm in the measurement of the radius 10 cm of a cylinder of fixed height 20 cm then error in the volume is
