If area of circle is equaled to 100pi what is the radius?
Area = pi*r2 So r = 20 inch gives area = 1256.64 sq inches.
When you try to figure out an area of a circle, you square the radius, then multiply it by pi to get the area of a circle. A radius square is radius x radius, or radius squared.
A circle with a radius of 4 cm has an area of 50.27 square cm.
The area of a circle with a radius of 7 cm is: 153.9 cm2
A circle with a radius of 20 yards has an area of 1,256.64 square yards.
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

If area of circle is equaled to 100pi what is the radius?
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.
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
Approximately 1,256.6 ft2
