Question

A5 cm x 11 cm rectangle sits inside a circle with radius of 12 cm.What is the area of the shaded region?Round your final answer to the nearest hundredth.5 cm12 cm11 cmmay you convert this into a decimal number please

Answer 1

Area of a circle = π x radius ^2 = π r^2

Replacing with the values given:

A C = π 12^2 = 452.39 cm^2

Area of a rectangle: Length x width

A R = 11 x 5 = 55 cm^2

To find the shaded region, subtract the area of the rectangle to the area of the circle:

452.39-55 = 397.39 cm^2
