So the equation for finding the area of a cyclinder is: area is cross/section X perpendicular length.
So for this you would do-
Pi x 4 to the power 2
To get the area of the circle
That is
16 pi / 50.265...
Then to get the volume of the cylinder you would times the answer you have just got by 3 (the perpendicular height)
Giving you the answer of
48 pi / 150.8cm^3
