A circle with a radius of 20 yards has an area of 1,256.64 square yards.

The area of a circle is computed by the formula A = pi * r2 (r is the radius of the circle)For a 20 foot circle, the radius is 10 feet and the area is 314.16 square feet.

Radius = 20/2 = 10 Area of circle = pi x radius x radius = 3.1415 x 10 x 10 = 3.1415 x 100 = 314.15 square units
