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:(

Step-by-step 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

the answer is: the length is 5/6 yards.

give me a or a 5 star rating if this is correct!
