If i remember the 'ol math class circle area is equal to radius squared times pi
so 20x20x3.14 = 1256 meters squared
A circle with a radius of 20 yards has an area of 1,256.64 square yards.
400 pi
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.
The area of a circle is calculated using the formula ( A = \pi r^2 ), where ( r ) is the radius. Given a diameter of 40 meters, the radius is ( r = \frac{40}{2} = 20 ) meters. Therefore, the area is ( A = \pi (20)^2 = 400\pi ) square meters. In terms of ( n ), it can be expressed as ( A = 400n ) if ( n = \pi ).
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

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

3.14*202
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
Oh, isn't that a happy little question! If the area of a circle is 100π, we can use the formula for the area of a circle, which is πr^2. So, 100π = πr^2. By solving for the radius (r), we find that the radius is 10 units. And since the diameter is just twice the radius, the diameter would be 20 units.
