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

1,256.6 square units.

3.14*202

Using 3.14 as Pi the area of circle is: 1256.0

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.

1256 inches squared

Approximately 1,256.6 ft2

Area of a circle = pi times radius squared

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

Circumference of a circle = 2*pi*radius or pi*diameter Area of a circle = pi*radius squared

A circle with a radius of 10 cm has an area of 314.16 square cm

20 yards.

20; the diameter of a circle is twice its radius.

855.21 square feet. A circle with a radius 70 would be (pi)(radius squared) = (3.1416) (70) (70) = 15,393.8 square feet. With a 20 degree angle that is 20/360ths of a circle, so multiply your circle area by 20 and divide by 360 = 855.21 square feet.

For A+ it's 20

The radius of this circle is 10 units.

Using 3.14 as Pi the area of circle is: 1256.0

If the circle is 20 ft radius, the area is π·20² = 1256.637 ft² If the circle is 20 ft diameter, the area is π·(20/2)² = 314.1593 ft² If the circle is 20 ft circumference, the are is π·(20/2π)² = 63.66198 ft²

The radius is 3.183

Divide the diameter by 2 to get the radius. Then use the standard formula for the area of a circle (area = pi x radius2).

radius = 20pi/2pi = 10 units area = pi*102 = 100pi square units
