If x = 16 feet and y = 8 feet, what is the area of the figure above ? use 3.14 for pi .

a. 153.12 feet^2

b. 178.24 feet^2

c. 228.48 feet^2

d. 52.56 feet^2

A

Step-by-step explanation:

You can probably figure out the rectangle of 16 by 8 so no explaining there. 16×8=128. You know that diameter of the cirkel is equal to y so 8. The diameter of a cirkel is two times its radius. so 8=2r. r=4. The area of a cirkel is calculated by the formula \pi×r^2. Fill in r=4 in \pi×r^2 gives us \pi×4^2=16\pi. You only have half of the cirkel so 16\pi/2=8\pi. 128+8\pi=153.12 which is A.
