There's no way to express area in feet - it needs to be square feet. A circle of radius 12" has an area of pi sq. ft. ~= 3.141 sq. ft. A circle of diameter 12" has area pi/4 sq ft ~= 3/4 sq. ft.
2.5 x 2.5 x 3.14 = 19.625 sqft
7850 sq ft. Formula is pi x R squared. Diameter of 100 means Radius (r) is 50. 50 squared (multiplied by itself) is 25000. Multiply THAT by the value of pi- or 3.14, and you get 7850 sq ft.
area of full circle = 400 sq. ft. if area = pi * radius2 then radius = square root ( area / pi ) = 11.284 radius (approx). = 22.568 diameter (approx).
First you determine the radius of the circle. If 6.6 feet refers to the diameter, divide that by 2 to get the radius. Then you use the standard formula for the area of a circle.
The area of a circle with a diameter of 9 feet is 63.6 sq ft (approx).The area of a circle with a diameter of 9 feet is 63.6 sq ft (approx).The area of a circle with a diameter of 9 feet is 63.6 sq ft (approx).The area of a circle with a diameter of 9 feet is 63.6 sq ft (approx).
It's a surface that has an area of exactly 1,000 sq ft. It can have any shape. If it happens to be a square, then each side of the square is about 31.6 ft long. If it happens to be a circle, then the diameter of the circle is about 35.7 ft.
132.7 sq ft, approx.
This would not be called a circle. IT would be called a ring. Sq Ft of outer ring - Sq Ft of inner ring = Sq Ft in between 113.04 - 12.56 = 100.48 sq ft
A circle with a diameter has an area of 50.265486543928724876568901 sq. ft.
Area 36 ft diameter circle = pi x radius squared = 3.1416 x 18 ft x 18 ft = 1017.87 sq ft
28.3
Diameter of the circle = 529.257 feet rounded to 3 decimal places
If the diameter is 80 ft then the area is 5026.54 sq ft
5.6433 ft radius or 11.2866 diameter
The diameter of the circle works out as 97.721 feet rounded to three decimal places
A circle with a 49 ft diameter would have an area of 1885.741 sq ft (to 3 dp)
