Answer:

B. 49,062.5 ft²

Step-by-step explanation:

The formula of an area of a circle:

[tex]A=\pi r^2[/tex]

r - radius

We have the diameter d = 250 ft. We know: d = 2r.

Therefore r = 250 : 2 = 125 ft.

Substitute:

[tex]A=\pi(125)^2=15625\pi[/tex]

[tex]\pi\approx3.14\to A=(15625)(3.14)=49062.5\ ft^2[/tex]
