area = 3.14 × r^2
Area = 3.14×r×r
So,
55 = 3.14×r×r
55/3.14 = r^2
16.18 = r^2
4.022 = r
Circumference = 2*3.14*r
So,
Circumference = 2*3.14*4.022
Circumference = 25.25816
Area = 3.14×r×r
So,
55 = 3.14×r×r
55/3.14 = r^2
16.18 = r^2
4.022 = r
Circumference = 2*3.14*r
So,
Circumference = 2*3.14*4.022
Circumference = 25.25816
