How to find the perimeter of a sector using arc length formula

The video tutorial explains how to find the perimeter of a sector of a disk with a radius of 11 cm and an angle of 10 degrees. It covers the concept of perimeter as the distance around a shape and introduces arc length as a component of the perimeter. The tutorial demonstrates how to convert degrees to radians and calculate the arc length using the formula s = r * θ. Finally, it combines the arc length with the radius to find the total perimeter, rounding the result to the nearest hundredth.

Explain the process of finding the arc length as described in the text.
