1 radian is equal to:
Correct answer: C. 57.3 degrees
- A. 57.1 degrees
- B. 57.2 degrees
- C. 57.3 degrees
- D. 57.4 degrees
Explanation
360 degrees = 2 π rads-> 1 radian= 360/2π->57.3 °.

About Angular Displacement
Angular displacement measures the change in a body’s angular position and is expressed in radians or degrees, with anticlockwise and clockwise directions assigned signs. It connects to arc length, angular velocity and angular acceleration, and must be distinguished from ordinary linear displacement in rotational motion.
