A circle with radius of 4 cm sits inside a circle with radius of 11 cm.
What is the area of the shaded region?
Round your final answer to the nearest hundredth.
4 cm
11⁰ cm

Area of the shaded region = 329.7cm

Explanation:

Area of circle = π r2

Area of smaller circle with radius of 4 cm = 3.14 * 4 * 4 = 50.24cm

Area of bigger circle with radius of 11 cm = 3.14 * 11 * 11 = 379.94cm

To calculate the area of shaded region,

Area of the shaded region = bigger region - smaller region

39.7 - 50.24 = 329.7cm

Area of the shaded region =

sure what is it? ^w^

the answer is 303.15 or 303
