The area of a circle is 49π cm2. Its circumference is

Let the radius if circle be r


Given, Area of circle = 49π cm2


Area of circle = πr2


πr2 = 49π


Since = 22/7


πr2 = 49π


r2 = 49


r = √49 = 7 cm


Radius of circle = 7 cm


Circumference of circle = 2πr


= 2 × π × 7 cm


= 14π cm


Circumference of the circle is 14π cm
