Question

What is the approximate area inside the rectangle but
outside the semicircle?

Answer 1

128 - 32pi

OR

27.469

Explanation:

The area of the rectange is 8 x 16 = 128

The area of the semicircle is pi * 8^2 divided by 2

(pi * 8^2)/2

(pi * 64)/2

pi * 32

So the area of the rectangle outside the semicircle is: 128 - 32pi

In approximate form it is: 27.469
