How many centimeters of arc is 30 degrees angle?

To calculate the arc length for a 30-degree angle, you need to know the radius of the circle. The formula for arc length (L) is given by L = (θ/360) × 2πr, where θ is the angle in degrees and r is the radius. For a 30-degree angle, the arc length would be L = (30/360) × 2πr = (1/12) × 2πr = (π/6)r. Thus, the arc length in centimeters depends on the radius you use.
