WebMay 11, 2010 · Please clarify your question next time.If it's 8 inches in diameter, the circumference would be as follows:Circumference of a circle = pi (sorry but I don't know how to type the symbol) x diameter = 3.14 x diameter (if you round pi)Therefore if diameter=8, circumference = 3.14 x 8 = 25.12 inches.If the 8 inches is the radius, you … WebIn two dimensions the answer is simply: as the radius increases, the area increases by the square of the increasing factor. That's a bit abstract, so let's give some examples. If the radius doubles, that's a factor of 2. The square of 2 is 4, so if the radius doubles the area is multiplied by 4. This is the example given in the video.
