The relationship between degree measure and radian measure is:

Aπ radian = 360°
Bπ radian = 180°
C2π radian = 180°
Dπ radian = 90°
Answer & Solution
Correct answer: B. π radian = 180°
A full circle subtends 2π radians at the centre, which equals 360°. So π radian = 180°. **From this:** 1 radian = (180/π)° ≈ 57°16′ and 1° = π/180 radian ≈ 0.01746 radian.
