A circle with a radius of 20 yards has an area of 1,256.64 square yards.
Radius: square root of (1256/pi) = 20 cm rounded to nearest integer
A circle with a radius of 20 yards has an area of 1,256.64 square yards.
Radius of a circle with 20' circumference = 20'/2pi = 3.18'Area of a circle with 3.18' radius = ((3.18')^2)pi = 31.8 square feet

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.
Using 3.14 as Pi the area of circle is: 1256.0
1,256.6 square units.
