|Activity: Areas of Regular Polygons and Circles|
|Go to:||http://www.keypress.com/.../PolygonCircleArea.zip (opens a new window)|
Students manipulate the number of sides in a regular polygon, develop a formula relating the area and perimeter of the polygon, and use their result to develop a formula relating the circumference and area of a circle. The link to the activity itself is to a zip file that contains both the activity in pdf format and the corresponding sketch.
This is a free sample activity from Exploring Geometry with the Geometer's Sketchpad.
