### How do you calculate radians?

How do you find radians on a unit circle? The radian measure of an angle is the ratio of the length of the arc to the radius of the circle (θ=sr) ( θ = s r ) . In other words, if s is the length of an arc of a circle, and r is the radius of the circle, then the central angle containing that arc measures radians.
