Correct answer: C. 57o18'
- A. 57o3'
- B. 57o3"
- C. 57o18'
- D. 57o18"
Explanation
1 radian = 180/π degrees ≈ 57°18′ It's the angle subtended at the center of a circle by an arc equal in length to the radius.

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.
