Pre Calc unit 3 Find the radius given the arc length and angle in degrees

The video tutorial explains the importance of using radians in calculations and demonstrates how to convert degrees to radians. It introduces the formula S = R * Theta and shows how to solve for R when given S and Theta. The tutorial also discusses when to approximate or round values, emphasizing the importance of leaving answers in terms of π unless specified otherwise.

Explain the process of finding R when S is given as 40 centimeters and Theta is π/9.
