Answer:

D, 1250 square feet

Step-by-step explanation:

Area of a circle:

[tex]\pi * r^2[/tex]

Diameter is twice the radius, so the radius is 20 ft.

Thus the area of grass is 400pi

Answer:

The answer is D

Step-by-step explanation:

You are basically looking for the area of this circle, the formula would be A=Pi*r^2. So plug the values in and it would be, A=3.14*400, we know the radius is 20 because the diameter is double that, and square the radius, this gives you 400.
