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

in a sphere the rate of change of surface area is

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.

The radius of spherical bubble is changing with time. The rate of change of its volume is given by :
