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

the circumference and area of a circle with a diameter of elleven feet are as follow. circumference:34.54 area:94.985
Pi is the number of times the diameter of a circle will fit into the circumference. Pi is not a circle, and does not have a circumference or area. To calculate a circumference USING pi, the circumference is diameter * pi. To find the area using pi, area = pi * radius * radius
Circumference = 48.262
radius = circumference/(2*pi)area = pi*radius2So Area in terms of Circumference is A = pi [C/2pi]2or (circumference)2/4 pi
The area of a circle that has a circumference of 16pi is: 201.1 units2
