WebJust as the full circumference of a circle always has a constant ratio to the radius, the arc length produced by any given angle also has a constant relation to the radius, regardless of the length of the radius. This ratio, called the radian measure, is the same regardless of the radius of the circle—it depends only on the angle.

WebJan 11, 2024 · A circle measures 360 degrees, or 2\pi 2π radians, whereas one radian equals 180 degrees. So degrees and radians are related by the following equations: 360°=2\pi radians 360° = 2πradians 180°=\pi radians 180° = πradians The relationship between radians and degrees allows us to convert to one another with simple formulas.
