Cylinder is a three-dimensional geometric figure with parallel congruent bases. The bases can be shaped like any closed plane figure (not necessarily a circle) and must be oriented identically. Oblique cylinder is a cylinder with bases that are not aligned one directly above the other. Right cylinder is a cylinder with bases that are aligned one directly above the other.
Volume of cylinder (both right and oblique) is $V=S_b{H}$, where $S_b$ is a surface area of cylinder base and H is a distance between the bases of a cylinder (cylinder height).

Right cylinder with a circular bases is a right circular cylinder.

Volume of a right circular cylinder is $V=\pi R^2 H$
Surface area of a right circular cylinder is $V=2S_{base}+S_{lateral}=2\pi R^2 +2\pi RH$
