The term "ring shaped" can be replaced with several different synonyms, depending on the context. A common synonym is "circular," which refers to any shape that is round and has no sharp corners or edges. Other synonyms include "annular," "round," "oval," "looped," "hoop-shaped," and "donut-shaped." Annular is a more technical term used to describe shapes with a circular cross-section and a hole in the center, such as a ring or a tube. Round and oval are more general terms that can be used to describe any shape with a circular or egg-shaped outline. The term "hoop-shaped" is typically used to describe objects that are circular and curved, but not necessarily perfectly round.
