The area of a circle is pi x radius2. You know the radius already since it's diameter/2 which is 8 inches. Your answer then is pi times 8 inches squared which is 64 times pi inches squared. pi is about 3.1415 so multiply that by 64 if you need to resolve the pi.

A circle with a 14 inch diameter has an area of 153.9 sq inches.
12.5664 Sq.In.

12 inches is the diamter so 6 inches is the radius. The area is 36Pi or about36x3.14 which is about 113 square inches

If 36 inches is the diameter the answer is: 7,068 square feet.
12 inches is the diamter so 6 inches is the radius. The area is 36Pi or about36x3.14 which is about 113 square inches
formula used is (pi)x(radius squared)= square inches (3.14)x(5x5)= 78.5 square inches
There are no square inches in an inch. Square inches are units of area and inches are units of length.
First find the radius = 12/(2*pi) = 1.909859317 inches Area = pi*1.9098593172 = 11.4591559 or about 11.5 square inches
3 inches
There are no inches in an square inch. Square inches are units of area and inches are units of length, the two can not be equated.
