So finally you see why math is important? Area=Pi X R X R where Pi=3.14159 R=radius of the circle. Lets say the circle is 2 feet in diameter. Then the area is Area=3.14159 X 1 X 1=3.14 Square Feet. Cool huh?

How many sq ft in a circle with a 12ft outer diameter and a 4ft inner diameter?
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
What is the area in feet of a 12 inch circle?
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.

(60,000 sq ft) / (43,560 sq ft / acre) = 1.3774 acre (rounded)
How many square feet is 24 inch circle?
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 do you find how many more square feet a 30 in circle is than a 18 in circle?
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.
