Deriving the Formula for Finding the Area of a Circle Brief Description: Students will work individually or in groups to derive the formula for the area of a circle.

The formula to find a circle's area $$ \pi $$ (radius) 2 usually expressed as $$ \pi \cdot r^2 $$ where r is the radius of a circle. The area of a circle is all the space inside a circle's circumference. In diagram 1, the area of the circle is indicated by the blue color. The area is not actually part of the circle.
