Right circular cylinder

A right circular cylinder is a cylinder whose generatrices are perpendicular to the bases. Thus, in a right circular cylinder, the generatrix and the height have the same measurements.[1] It is also less often called a cylinder of revolution, because it can be obtained by rotating a rectangle of sides ${\displaystyle r}$ and ${\displaystyle g}$ around one of its sides. Fixing ${\displaystyle g}$ as the side on which the revolution takes place, we obtain that the side ${\displaystyle r}$, perpendicular to ${\displaystyle g}$, will be the measure of the radius of the cylinder.[2]

In addition to the right circular cylinder, within the study of spatial geometry there is also the oblique circular cylinder, characterized by not having the geratrices perpendicular to the bases.[3]

Examples of objects that are shaped like a right circular cylinder are: some cans and candles.
