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 rate of change of volume of a sphere is equal to the rate of change of its radius, then its radius is equal to

If the rate of change of area of a circle is equal to the rate of change of its diameter, then its radius is equal to

If the radius of the circle changes at the rate of 0.04 cm//sec , then the rate of change of its area, when radius is 10 cm, is

The radius of a cylinder increases at the rate of 1 cm/s and its height decreases at the rate of 1 cm/s. Find the rate of change of its volume when the radius is 5 cm and the height is 5 cm. If the volume should not change even when the radius and height are changed, what is the relation between the radius and height?

If the rate of change of volume of a sphere is the same as rate of change of its radius,then radius,is equal to

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

The radius of a cylinder is increasing at the rate 2cm/sec. and its altitude is decreasing at the rate of 3cm/sec. Find the rate of change of volume when radius is 3cm and altitude 5cm.

The radius of a cylinder is increasing at the rate 2cm/sec. and its altitude is decreasing at the rate of 3cm/sec. Find the rate of change of volume when radius is 3 cm and altitude 5 cm.
