👉 In mathematics, radians are a system of measuring angles based on the circle. The unit of angle is called "radian," and it is defined as the length of the arc in a full circle that subtends an angle with the radius of the circle. The formula for converting from radians to degrees is: \[ \text{Radian} = \frac{\pi}{180}\cdot\text{Degree} \] Where: - \(\pi\) ≈ 3.1
