Question

A circle with a radius of 2 cm sits inside a circle with radius of 4 cm. What is the area of the shaded region? Round your final answer to the nearest hundredth.

Answer 1

Area of smaller circle is a = pi times 2^{2} = 4 pi

Area of larger circle is A = pi times {4}^{2} = 16 pi

The area of the shaded region is: 16 pi - 4 pi = 12 pi

and 12 times pi= 37.70 cm2

Answer 2

The area of the shaded region is 37.70 cm2
