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.
if the pizza is round then you use Pi X 7.5 X 7.5
