Question

What is the area of the shaded portion to the nearest hundredth?

Answer 1

13.72 square meters

Explanation:

So first, we get the area of the whole rectangle:
`4 * 5 = 20 m`

Since the area of a half-circle is
`(\pi r^(2) )/(2)`, and the radius of the circle is
`(4)/(2)` = 2, we have
`2\pi` which is around 6.2831.

20 - 6.2831 = 13.7169m, and rounded is 13.72 square meters.
