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.
