The answer is A. 314,000,000 ft2 

The area (A) of the circle with radius r is:
A = π r²

We have:
r = 10 000 ft
π = 3.14

A = 3.14 (10 000)² = 3.14 100 000 000 = 314 000 000 ft²

the answer is 314,000,000 ft2, you would multiply 10,000 by 2 and divide by pi i belive. I'm not the best at math but I hope this helps.
