 | The word "round" is used colloquially in many ways, mostly in the sense of beeing “round like a circle” (→circular or ring-shaped), “round like a roll or drum” (→cylindrical) or “round like a ball” (→spherical) and often only as a distinction from the “regular” shape of the objects, e.g. beeing “round, not rectangular” or beeing “round, not flat” or being “round and not having edges”. So possible meanings of “round” are:
- ↑ In the mathematical sense ellipses and circles are special types of ovals.
- ↑ In the mathematical sense rings, cylinders, cones and spheres are all solids of revolution.
