=>

♎The radian is a unit of measure for angles used mainly in trigonometry

It is used instead of degrees. Whereas a full circle is 360 degrees, a full circle is just over 6 radians

⛎ A full circle has 2π radians (Roughly 6.28) As seen in the figure above, a radian is defined by an arc of a circle.
