Question

Find the Area of the figure below, composed of a rectangle with a semicircle removed from it. Round to the nearest tenth place.

Answer 1

Below

Explanation:

Area of WHOLE rectangle = 9 x 6 = 54 units^2

now subtract the area of the semicircle with radius 3

whole circle is pi r^2 ( one-half of this is 1/2 pi r^2)

54 units^2 - 1/2 pi r^2

54 - 1/2 * pi * 3^2 = 39.9 units^2
