A cylinder is a solid that has two bases that are congruent connected by a curved surface.
The axis of a cylinder
is the connecting the center of the bases. The height of a cylinder is the perpendicular distance between the bases. The radius of the cylinder is the of a base.
If the axis of a cylinder is not perpendicular to the bases, the cylinder is said to be an oblique cylinder
If the dimensions of a cylinder are known, its and can be calculated.
