A = pi*r^2

A = pi*(500)^2 .... Note: the radius is half the diameter

A = pi*250000

A = 250000pi

A = 250000(3.14)

A = 785000

So the answer is choice D. 785,000m^2

Area of Circle is πr^2
If diameter of circle is 1000m then radius is 500m or one half. Then plug into equation.
A=πr^2
A=π500^2
A=250000π or approx. 785,000m^2
