If: pi*radius2 = 81*pi sq ft
Then: radius = 9 feet
Circumference = 2*pi*9 = 56.549 feet rounded to 3 decimal places
The area of a circle with a 12-foot circumference is about 11.46 square feet.
If the diameter of a circle is 268 feet:Circumference = 841.9 feetArea = 56,410 square feet
The area of a circle with radius r is A = pi.r^2. The radius of a circle with circumference C is r = C/(2pi) since C=2.pi.r. So the radius of a circle with circumference 16.5 feet is r = 16.5/(2pi) ≈ 16.5/(2x3.1416) ≈ 2.626 feet. Thus this circle has area A = pi.r^2 ≈ 3.1416 x (2.626)^2 ≈ 21.7 square feet.
If the area is a circle, the circumference is about 7,400 feet.
r = 34.83 ft C = 218.9 ft
If the circumference of a circle is 16pi feet, the area is: about 201.1 square feet.
The circumference is about 15.04 feet.
A circle with a radius of 80 inches has an area of 139.6 square feet A circle with a circumference of 40.5 feet has an area of 130.5 square feet
A 45-foot circumference circle has an area of: 161.1 square feet.
A circle with a circumference of 70 feet has an area of 389.93 square feet.
The radius of the circle is 4.296739857 and its circumference is 27 feet rounded
The area of a circle with a 12-foot circumference is about 11.46 square feet.
A circle with a 60-foot circumference has an area of 286.48 square feet.
If you mean as in the area of a circle that has a circumference of 518.519 feet Then its radius is about 82.5 feet The area of the circle: pi*82.5^2 = 21,382 square feet rounded
The circumference is 21.269 feet.
The area of a circle with a radius of 18.4 feet is approximately 1,061 square feet. The circumference of the same circle is approximately 115.7 feet.
