Answer: 236.715
Explanation:
1. Find the area of the middle rectangle.
Use A = bh
A = (4)(15)
A = 60
2. Find the area of the two semicircles (which equals one circle)
Use A = πr²
The diameter is given.
D = 2r
15 = 2r
r = 7.5
A = π(7.5)²
A ≈ 176.715
3. Add the area of the rectange and circle.
60 + 176.715 = 236.715
