in a sphere the rate of change of surface area is

The side of a cube is equal to the radius of a shpere. If the side and the radius increase at the same rate, then the relation between the rates of change of surface areas of the cube and sphere respectively is

If the rate of change in volume of spherical soap bubble is uniform then the rate of change of surface area varies as

If the time rate of change of the radius of a sphere is (1)/(2pi) , then the rate of change of its surface area(in square cm), when the radius is 5 cm , is-

The volume of a sphere increse at the rate of 20 cm^3 /sec. Find the rate of change of its surface area when its radius is 5cm.

The volume of a sphere increase at the rate of 20cm^(3)//sec . Find the rate of change of its surface area when its radius is 5 cm

Find the rate of the change of surface area of a sphere when its radius is increasing at the rate of 3/pi cm/min and its radius is 1 cm.

If the rate of change of surface area of a sphere is 4m^2 /sec , then the rate of change of volume when the radius is 3m is.
