Hey friend ,
Here is your answer ,
______________________________________________________________
The Radian is a angle for circular measure. If the central angle in the circle has radius of length 1 and length of arc is 1, then the angle is 1 rad.
The circumference of a circle is C=2πR, there R is the radius of a circle. If R=1, then C=2π.
The angle of whole arc is 360°, so 2π=360° and 1 rad = 1/(2π) × 360° ≈ 1/(6.28) × 360° ≈ 57.3°.
