Answer:
C is the answer, as wind turbines are more expensive
CF=EC=DC
2CF=CD
CD = 20 in.
Area of circle = πr²
= 64π
The cord will subtend a semicircle of diameter 8", radius 4". The area of this semicircle:
1/2 πr²
= 0.5 x 4² x π
= 8π
Area of larger region = area of circle - area of semicircle
= 64π - 8π
= 56π inch²
