What is the formula for arc length with radius and theta

The video tutorial explains the concept of angles as a measure of rotation between two rays, using Theta in degrees and radians. It introduces radians in the context of circles and defines arc length as the length of a radius wrapped around a circle. The formula for arc length, s = r * Theta, is presented, emphasizing that Theta must be in radians. The tutorial concludes with a practical example to calculate arc length using the given formula.
