# Finding the Area of a Circle

Students learn how a circle can be formed into a parallelogram and rectangle so the area is derived as A =πr2.  As learning progresses students practice finding the area of a circle in terms of π and calculate the radius or diameter when the area is given.The start of the lesson recaps finding the area of a triangle and parallelogram.  In the plenary students are challenged to use to square and circle of equal area to find the perimeter of the square.
##### Differentiated Learning Objectives
• All students should be able to calculate the area of a circle to 3 significant figures.
• Most students should be able to calculate the area of a circle as a multiple of π.
• Some students should be able to solve problems involving the area of a circle.
