What is the total number of degrees in a full circle?

A full circle consists of 360 degrees. This measurement is fundamental in geometry and is widely used in various applications ranging from navigation and engineering to art and design. The concept of a 360-degree circle dates back to ancient civilizations, which divided the circle into equal parts for easier calculation and representation of angles.

Understanding that a full circle is represented by 360 degrees is essential, as it serves as a basis for measuring angles in both degrees and radians. For instance, in trigonometry, a full rotation corresponds to 2π radians, which is equivalent to 360 degrees. This relationship is crucial for various calculations in mathematics and physics, especially when dealing with rotational motion and periodic phenomena.

The other options, while numerical values, do not represent the measurement of a complete revolution around a point. For example, 180 degrees corresponds to a half-circle, while 540 and 720 degrees represent more than one full circle and are used for understanding multiple rotations around a central point.
