Radians - determine angle from arc length and radius - Question As well as using degrees, angles can also be measured using what are known as radians (rad). Radians are defined with relation to a circle, with there being exactly 2\(\pi\) rad in one full circle.

The below diagram shows a circle with a radius of 5 m. There is an angle \(\theta\) which corresponds to an arc length of 10 m on this circle.
