Question

A circle has an area of 36π square meters.

What is the circumference of this circle?


6π meters


12π meters


18π meters


36π meters

Answer 1

12π meters

Explanation:

Area of circle = Pi*r^2 -> 36*Pi = Pi*r^2

So, radius of circle (r) = 6 m

Circumference of circle = 2*Pi*r = 2*Pi*6 = 12Pi m
