Relationship between Degree & Radian
2π radian =360o = One revolution
Or 1 radian = 180°/ π = 57° 16′ approx.
Also, 1° = (π / 180) radian = 0.01746 radian approx.
Degree to Radian Formula
Numerical: Convert 60° to radian form & Convert π into degree.
Solution: Lets first convert 60° to radian
Radian measure = (π/ 180) × Degree measure = (π/ 180) * 60° = π/3 radian
Now let’s convert π into degree.
Degree measure = (180/π) x Radian measure = 180/π * π = 180o
