Lesson Plan: Areas of Circular Sectors Mathematics

This lesson plan includes the objectives, prerequisites, and exclusions of the lesson teaching students how to find the area of a circular sector and solve problems that relate this area to the arc length and perimeter of the sector.


Students will be able to

  • recognize the formulas for calculating the area of a sector when the measure of the arc is given in degrees or radians,
  • calculate the area of a sector,
  • solve related problems involving areas and perimeters of sectors.


Students should already be familiar with

  • radians,
  • calculating arc length.


Students will not cover

  • circular segments.
