If the area of a circle increases uniformly, then show that the rate of increment of its circumference is inversely proportional to its radius.

If the area of a circle increases uniformly, then show that the rate of increment of its circumference is inversely proportional to its radius.

(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.

(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 circumference is iversely proportional to its radius.

If the area of circle changes uniformly w.r.t. time , show that the rate of change of its circumference varies iversely as its radius.

If the radius of circle is increasing at the rate of 0.5 cm/s, then the rate of increase of its circumference is______

The radius of a circle is increasing at the rate of 0.7 cm/s. What is the rate of increase of its circumference ?
