Question

Find the approximate area of the shaded region of the

figure below.
A: 489.44 cm2
B: 181.72 cm2
C: 27.86 cm2
D: 49.07 cm2

Answer 1

D:49.07

Explanation:

The area of a rectangle is LxW and the area of a semi circle is (πr^2)/2

Because you are finding the area of the pieces around the semicircle, you would subtract the area of the semicircle from the area of the rectangle:

(LxW)-(πr^2)/2

Length=14cm, Width=9cm

R is the radius of the semicircle which is half the length, r=7cm

(14x9)-((π7^2)/2= 49.07
