# Area of a Sector

##### This Area of a Sector activity & project also includes:

Young geometers derive the formula for the area of a sector of a circle. As they work through a series of problems, they find the area of one piece of a pizza if it is divided into eight equal pieces. Learners then investigate how changing the central angle of a piece of pizza affects the area of the piece, then generalize their results to find the area of a sector of any given central angle measure.
