Question

given that the area of a circle s 38.5 sq.m , find its circumference

Answer 1

$\large \tt AHOY!! \:$

given the area of the circle = 38.5cm²

therefore πr² = 38.5cm²

=> 22/7 × r² = 38.5cm²

=> r² = 38.5/1 × 7/22

=> r² = 12.25

=> r = √12.25

=> r = 3.5cm

now, we have to find it's circumference.

circumference of the circle = 2πr

= 2 × 22/7 × 3.5

= 2 × 22/2

= 22cm
