What is circle shape?

A circle is a two-dimensional shape that is defined as the set of all points in a plane that are equidistant from a given point called the center. The distance from the center to any point on the circle is called the radius. The diameter of a circle is a line segment that passes through the center and has both endpoints on the circle.

The formula for calculating the circumference of a circle is 2πr, where r is the radius. The formula for calculating the area of a circle is πr².

Circles are a fundamental shape in geometry and are used in many mathematical and scientific applications. They are commonly found in nature in objects such as wheels, coins, and fruit. Circles have an infinite number of symmetries and are often used to represent concepts such as unity and perfection.
