A cylinder, can, barrel, tube or coin features a circular base combined with some height for a three-dimensional object. The volume of a cylinder with height
h
and radius
r
is given by
π
2
r
h
(base area × height). The top area equals the bottom area,
π
2
r
(the area of the circle). The curved surface area is
2πrh
(circumference × height).
