Silindri sisepiiranguks on selle läbimõõt, ja koondpinnal, mis koosneb kahest paralleelsest mittekoaksiaalsest silindrist, on rohkem kui üks sisepiirang (kaks läbimõõtu, nende telgede vaheline kaugus ja 0° nurk).
The intrinsic characteristic of a cylinder is its diameter which is a size, and in the collection surface, constituted by two parallel and not coaxial cylinders, there are more than one intrinsic characteristic (two diameters, the distance between their axes and the angle of 0°).
