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 , where 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
Surface area of a right circular cylinder is
