A circle with a 7 inch diameter has an area of 38.48451.
Using 3.14 as Pi the area of circle is: 314.0
you divide by pi (3.14) then take the square root, then multiply by 2 and multiply by pi (3.14)...in that order i.e. if you have a circle with area of 314 square inches, you take the 314 and divide by 3.14...you get 100...then you take the square root of 100...you get 10...then you multiply by 2...you get 20...then you multply by 3.14...you get 62.8 inches...thats the circumference of a circle with an area of 314 square inches
Approximatly 50inches
The area is 314 cm2
Using pi as 3.14 it works out that the diameter is 20 cm
Using 3.14 as Pi the area of circle is: 314.0
Circumference = 314 inches implies radius = 49.97 inches and so area = 7846.02 sq inches (approx).
100pi, or approximately 314.

Tells you the answer is 2*sqrt(314*pi) inches, which is approximately 62.82 inches Seriously though. Use metric units in maths it makes everything just work!
