The radius of a circular plate increases by 2% on heating. If its radius is 10 cm before heating, find the approximate increase in its area.

The radius of a circular plate is increasing at the rate of 0.01cm/sec when the radius is 12 cm. Then the rate at which the area increases is

The radius of a circular plate is increasing at the rate of 0.01 cm/sec when the radius is 12 cm. Then the rate at which the area increases is

If the radius of a circle is increased by 6 % , find the percentage increase in its area

The radius of a circular plate is increasing at the rate of 0.01 cm/s when the radius is 12 cm. Then the rate at which the area (in cm^(2)//s ) increases is -
