In this lesson, we will learn how to find the arc length and the area of a sector given the angle measure in degrees.

Students will be able to

recognize the formulas for calculating arc length when the measure of the arc is given in degrees,
calculate the length of a sector’s arc,
calculate the perimeter of a sector,
calculate the radius of a sector when given the measure of the arc and the length of the arc (or the perimeter),
recognize the formulas for calculating the area of a sector when the measure of the arc is given in degrees,
calculate the area of a sector,
solve related problems involving areas and perimeters of sectors.
