Question

The area of a circle is 616 cm find the circumference

Answer 1

Answer: 88 cm

Step-by-step explanation:

Area of Circle = πr2

πr2 = 616

22/7 x r2 = 616

r2 = 196

r = 14 cm

Circumference = 2πr

2 x 22/7 x 14 = 88cm

Answer 2

Answer:

Step-by-step explanation:

22/7×r^2=616

r^2=616×7/22

r=13cm.

Circumference=2×22/7×r

=2×22/7×13

=81.64cm
