Answer:
<h2>B. 49,062.5 ft²</h2>
Step-by-step explanation:
The formula of an area of a circle:

r - radius
We have the diameter d = 250 ft. We know: d = 2r.
Therefore r = 250 : 2 = 125 ft.
Substitute:


2^6 (or two to the sixth power) is equal to 4^3, which equals out to 64.
Different regular shapes have certain formulas that you use to find their volume. For example
volume of a cube is Base x Width x height
Volume of cylinder is pie r^2 x h
etc...
