Question

What is the circumference of a circle with an area of 132.665 square cm?

Answer 1

approximately 40.83 cm.

Explanation:

A = πr^2

132.665 = πr^2

132.665/π = r^2

Take the square root of both sides: r is approximately 6.50.

C = 2πr - plugging that value for r in you get a circumference of approximately 40.83 cm.
