Answer:

502,655m^2

Step-by-step explanation:

400 is radius

A=(pi)r^2

400^2*pi

A=502,655
The answer is 502,655 because 800 is the diameter of the circle and we need the radius. The radius is half of the diameter so 800/2 is 400. The area of a circle is pi*radius^2. So pi*400^2 is the equation to use to get your answer.
