Solution :

  • Area of circle = 616 cm

We need to calculate the radius.

We know that :

  • A = πr^2

Here,

  • A is area
  • r is radius

Substituting values :

> 616 = (22/7) × r^2

> 616 = 22r^2 / 7

> 616 × 7 = 22r^2

> 22r^2 = 4312

> r^2 = 4312 / 22

> r^2 = 2156 / 11

> r^2 = 196

> r = 14
