RADIANS Radians, like degrees, are a way of measuring angles.

And because we are dealing with the unit circle here, we can say that for this special case, Remember:

Arc Length Start with the formula for radian measure … … and multiply both sides by r to get … Arc length = radius times angle measure in radians.
