its 2 pie r squared BUT you have to add back the base (a circle) which is pie r2 The original formula is 4 pie r squared Your new formula is (2 pie r squared + pie r squared)
It isn't. That is the formula for the AREA of a circle!
[2 x pie x radius] or [pie x diameter]
If the pie is a perfect cylinder then the formula for volume would be: Area= (height)(pi)(radius^2)
circumference = pi multiplied by the diameter
