Question

If the area of a circle is 616 cm2, then what is its perimeter?

Answer 1

The circumference of circle is 32 pie cm.

Answer 2

Area of the circle = 616 cm^2

To find the radius of the circle, the equation formed is
22/7 × r^2 = 616 cm^2 (where r is the radius)

On solving the equation, we will get r as 14 cm.

Hence, the perimeter of the circle
= 2 × 22/7 × 14cm
= 88 cm.
