A unit circle has radius 1, and thus circumference .
Since an angle of is one eighth of a whole turn, the length of an arc that subtends an angle of
radians will be one eighth of the whole circumference:
In fact, the radians have the property that, in the unit circle, the length of the arc is exactly the measure of the angle. In general, you have
where l is the length of the arc, r is the radius and is the angle in radians. So, if
, you have
