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.
The diameter is twice the square root of (1000/pi) feet.
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.
132.7 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).The area of a circle with a diameter of 9 feet is 63.6 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 49 ft diameter would have an area of 1885.741 sq ft (to 3 dp)
There are: 16*pi or about 50 square feet
A circle with a diameter has an area of 50.265486543928724876568901 sq. ft.
How many sq. Ft. Is in a 33 ft.diameter circle
Area 36 ft diameter circle = pi x radius squared = 3.1416 x 18 ft x 18 ft = 1017.87 sq ft
The formula for the area (A) of a circle is A = π r2 - where r is the radius. The diameter (d) of a circle is twice the radius. The area of circle having a diameter of 24 ft is A = π 122 = 144π = 452.39 sq ft (2dp)
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
