The word round can have several meanings, such as “round like a circle” (→circular or ring-shaped), “round like a roll or drum” (→cylindrical) or “round like a ball” (→spherical). It can also serve as a distinction from the usual shape of the object in question, e.g. “round, not rectangular” or “round, not flat” or “round, without edges”. More precise meanings of the word round are generally preferrable:

oval^[1]	elliptical	circular	polygonal	revolution- shaped^[2]	ring- shaped	cylindrical	(truncated-) conical	(hemi-) spherical	polyhedric	curved

↑ 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.
