A. 314,000,000 ft^2
B. 100,000,000 ft^2
C. 1,256,000,000 ft^2
D. 62,800 ft^2

Answer 1

The answer is D.

Answer 2

D. 62,800 ft^2

Answer 3

Area= Pi * Diameter

The Diameter is twice the size of the Radius. So if the radius is 10,000 times it by 2 to find the Diameter and then plug the number in.
