The term "round" refers to a shape that is circular and has no corners or edges. Common examples of round objects include coins, plates, and balls. In geometry, a round shape is often represented by a circle, which is defined as the set of all points that are equidistant from a central point, known as the center. In addition to its geometric meaning, "round" can also describe the process of adjusting numbers to make them simpler. For instance, rounding the number 4.6 to the nearest whole number results in 5. This technique is often used in mathematics to make calculations easier and more manageable.
