Question

Find the circumference of a circle whose area is 452.16 square meters ( ue 3.1416 as the value of

Answer 1

Area of circle, πr² = 452.16

πr² = 452.16

r² = 452.16/π,            π ≈ 3.1416

r = √(452.16/π) = √(452.16/3.1416) ≈ 11.997

Circumference  = 2πr

C = 2*3.1416*11.997

C ≈ 75.38

Circumference is ≈ 75.38 m.

Hope this helps.
