1 acre = 43,560 square feet

So you have a circle with an area of 43,560 square feet.

The area of a circle is (pi) R2 . 'R' is the radius ... half of the diameter.

Area = 43,560 = (pi) R2

Divide each side of the equation by (pi):

43,560/pi = R2

Take the square root of each side

R = sqrt(43,560/pi)

Double each side:

Diameter = 2 x sqrt(43,560/pi)

The diameter is 235.5 feet (rounded)
