Area of a circle = pi*radius2
Area of circle = Pi x diameter2/4 = 3.142 x 49/4 = 38.49 sq ft
441pi/4 sq ft
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.
Area of circle = Pi x diameter2/4 = 153.96 sq ft for a 14 ft 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).
Area of 30 inch circle = pi*302 sq inches Area of 18 inch circle = pi*182 sq inches Difference = pi*(302 - 182) = 576*pi sq inches 1 sq foot = 1 ft*1 ft = 12 inches*12 inches = 144 sq inches so 576*pi sq inches = 576/144 *pi sq ft = 4*pi sq ft = 12.57 sq 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
There are: pi*2 squared = 12.566 square feet to 3 dp
a 24 inch circle is a 2 ft diameter circle, or a 1 ft radius circle. the area of a circle is pi * r squared, so 1 ft squared is 1 sq ft. Times pi (=3.14159) is 3.14159 sq ft
4 x Pi, or about 12.5 square feet12.56637 sq. ft.
The answer is in the question! 12 sq ft!
Area 36 ft diameter circle = pi x radius squared = 3.1416 x 18 ft x 18 ft = 1017.87 sq ft
