Question

Can someone help me I’m having trouble finding the area of the shaded region in each figure and round the answer to two decimal places and I have to use 3.15:(

Answer 1

Explanation:

Area of a Semi Circle

Area = 1/2 pi r^2

r = d/2

r = 3/2

r = 1.5

Area = 1/2 3.14 * 1.5^2

Area = 1/2 * 3.14 * 2.25

Area = 3.5325

Area of Rectangle

L = 12 Yd

W = 4 Yd

Area = L * W

Area = 12 * 4 = 48

Total Area = 51.5325
