Final answer:

A detailed explanation of the definition and properties of a circle in mathematics.


Explanation:

A circle is a plane figure bounded by a single curved line, with every point equidistant from the center. The circumference of a circle is calculated by multiplying 2π by the radius.

Another way to define a circle is as the set of all points in a plane equidistant from a common point. This distance is the radius of the circle.

Remember, in a circle, every angle is measured to be 360 degrees, and the relationship between the radius, diameter, and circumference is fundamental.
