Students are guided though the derivation of the Area of a Circle formula by approximating a circle from its sectors.  Once the formula is derived there are several examples provided for the teacher to model its application in calculating the area of a circle and semi-circle. 

Differentiated Learning Objectives

• All students should be able to derive the formula for the area of a circle.
• Most students should be able to derive and apply the formula for the area of a circle.
• Some students should be able to calculate the area of a semi-circle.
