The area of a 6-foot diameter circle is about 28.274 square feet. A = pi r2 (r = 6/2 = 3) A = (3.1416)(32) = approximately 28.274
A circle that is 4 feet 6 inches in diameter has an area of: 15.904 square feet.
9pi (about 28 and one quarter) square feet.
A 45-foot diameter circle has an area of 1,590.4 square feet.
There are about 38.48 square feet in a 7' diameter circle
if the diameter is in feet then multiply the diameter by pi 38 x 3.14159 = 119.38042 square feet if the diameter is in inches then dividethe inches by 12 then multiply the diameter by pi 38 ÷ 12 = 3.16666 x by 3.14159 = 9.94835 square feet
A circle that has an area of 78.5 square feet has a diameter of 10 feet.
1356.48 sq mt Another answer in square feet is : The formula for the surface area of a sphere is 4 x pi x radius squared. The radius is half the diameter, or 3 feet. The radius squared is therefore 9 square feet. The surface area is then 4x3.1415x9 square feet or 113.09 square feet.
The diameter is 4.222 feet.
