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.

Diameter = 20 inch => radius = 10 inches = 10/12 feet. So area = pi*(10/12)^2 = 2.1817 sq feet approx.

Square footage is called "area". To find the area of a circle: A = pi x r2 So for a circle with a 10-inch diameter (which means a 5-inch radius): A = 3.141593 x (52) So the area = 78.54 inches

Area = pi x radius squared where pi = 3.1416 radius = diameter/2 = 10 ft area = 3.1416 x 10 x 10 = 314.16 sq ft.

A circle that has an area of 78.5 square feet has a diameter of 10 feet.

The answer depends on the square!

78.54 square units.

78.5 square feet.

Area of the circle is about 10 square units

Knowing that the area of a circle is its radius squared times Pi, the area of a 10 ft radius circle is 100*Pi square ft, or about 314 square feet.
