If the volume of a sphere is increasing at a constant rate, then the rate at which its radius is increasing, is

If the volume of a sphere increases at a constant rate, then the rate at which its radius increases, is-

The volume of a sphere is increasing at the rate of pi cm^(2)//sec . The rate at which the radius is increasing is ……….., when the radius is 3 cm.

The volume of the sphere is increasing at a constant rate. Then the radius is increasing at a rate

The volume of a sphere is increasing at the rate of 8cm^(3)//s . Find the rate at which its surface area is increasing when the radius of the sphere is 12 cm.

The radius of a circle is increasing at a rate ((dr)/(dt))=alpha . Find the rate at which its area is increasing when radius is equal to 3 m.

The volume of metallic hallow sphere is constant. If the order radius is increasint at thed rate of V cm/sec. Then the rate at which the inner radius increasing when the radii are a+d,a is

The volume of a metal hollow sphere is constant. If the outer radius is increasng at the rate of 1/4 cm per sec. The rate at which the inner radius is increasing when the radii are 8 cm and 4 cm repectively is

The volume of a cube is increasing at a constant rate. Prove that the increase in its surface area varies inversely as the length of the side.

(i) The radius of a circle is increasing at the rate of 5 cm/sec. Find the rate of increasing of its perimeter. (ii) If the area of a circle increases at a constant rate, then show that the rate of increase of its circumference is inversely proportional to its radius.
