Difference between cylinder and cone formula
seropon [69]
If your trying to find area....
Cylinder formula is
V= (Pie) 3.14 X r2 X h
[volume = pie 3.14 times the radius squared times the height]
Cone formula is
V= (Pie) 3.14 X r2 X h / 3
[volume = pie 3.14 times the radius squared times the height then divide that answer by 3 ]
