This geometry and trigonometry video tutorial explains how to calculate the arc length of a circle using a formula given the angle in radians the and the length of the radius. It also explains how to calculate the sector area in terms of pi or in radians. In addition, it also explains how to determine the area of a sector of a circle using an equation where the angle is given in degrees instead of radians. This video contains plenty of examples and practice problems.
