Question

A circle with radius of 2 cm sits inside a 11 cm x12 cm rectangle What is the area of the shaded region?

Answer 1

119.4 cm^2

Explanation:

Area of a circle is
`\pi` x radius^2, and the area of a rectangle is length * width. 11 cm x 12 cm = 132 cm^2 (rectangle's area). The circle's area would be
`\pi` x 2^2 which would equal 12.56637061 cm^2 (left unrounded until the end). Then subtract 12.56637061 from 132 cm^2 and that would equal 119.4 cm^2 rounded to the tenth.
