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

Area of a circle = pi*radius squared
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

how many square feet in 1500 by 16 feet
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.
There are: 16*pi or about 50 square feet
