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. 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.

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.

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