Question

A circle is drawn within a square as shown.

What is the best approximation for the area of the shaded region?

Use 3.14 to approximate pi.

Answer 1

Explanation:

`\text{The shaded area is the area of the square minus the area of the circle.}\\ \\ A=28^2-\pi 14^2\\ \\ A=784-196\pi\\ \\ A=784-196(3.14)\\ \\ A=168.56in^2`
