From your post, I'm not sure you have an actual circle. If not, we need more information before we can give you an answer.

Re: acres in a circle
Pi(R²)= area
3.14 * 900²= area
3.14 * 810,000= 2,543,400
ft²/acre= 43560
2,543,400/43560= 58.39

Re: acres in a circle
ok, the area of the circle is 20 acres. What is the radius?
Since I don't know how to do the equasions an explaination would help for future projects.
Anyone interested in helping me with the answer to this and to the explaination can email me at [link removed ]

The area of a circle is pi*r², so divide by pi (3.14159) and take square root,
526.6 ft radius
