How many degrees are there in a circle?

A circle has 360 degrees.

Every circle can be divided into 360 units called degrees.

One full circle rotation has 360 degrees.

A circle is defined as a set of all points that are a fixed distance (the radius) away from a central point (the centre). And the distance around a circle is called the circumference. To measure the angle of a full rotation around the circle, we divide the circumference by the radius, and we get the constant ratio of 2π. 

Therefore, the degree measurement of a full rotation around the circle is 360°.
