Question
What is the approximate radian equivalent of 1 degree?
Correct Answer
Option B is the correct answer.
Detailed Explanation
Since 180° is equal to π radians, 1° = π/180 rad. Using π ≈ 3.1416, 1° ≈ 3.1416/180 ≈ 0.01745 rad, which rounds to 0.0175 rad.
Hint
Recall that 180° = π radians. Divide both sides of this equation to find the value of 1° in radians.
