Finding the Circumference of a Circle

 

Students learn about finding the circumference of a circle as a multiple of π and as a decimal correct to 3 significant figures.

As learning progresses students are challenged to find the perimeter of semi-circles and sectors.

Differentiated Learning Objectives
  • All students should be able to find the circumference of a circle as a multiple of pi when the diameter is given.
  • Most students should be able to find the circumference of a circle to 3 significant figures.
  • Some students should be able to calculate the arc length of a sector.
