Well... According to the formula a 4" circle (pipe) would have an area of 12.56". An 8" circle would have an area of 50.24". Now you may say, "Whoa! How can that be?"

Maybe it can't be. Maybe I have the formula wrong. I'm just going from memory, but before you assume the formula is wrong... Do this... Go out and see if you can eat half a 16" diameter pizza faster than a friend can eat a full 8" diameter pizza. I think it will become more clear. Besides it will give you a good excuse to go out for supper!
