A circle is a geometric figure that is round and has no corners or edges. It is created by drawing a curve, called a circumference, around a central point called the center or focus. The distance from any point on the curve to the center remains constant, which means that all points are equidistant from the center. Circles can be drawn with any radius and have many properties and formulas associated with them such as area, circumference, pi, etc. They also occur naturally in nature, for example, sun, moon, planets, fruits like apple or orange, etc. In addition to this, circle is often used metaphorically to describe something that is endless or continuous, perfect, and so on.
