The video tutorial explains how to use the formula s = r * Theta to solve for Theta when given values for s and r. The instructor walks through an example problem where s is 3 meters and r is 1 meter, demonstrating how to isolate and solve for Theta by dividing both sides of the equation by r. The solution shows that Theta equals 3 radians. The tutorial concludes with a brief summary of the steps taken to reach the solution.
