Illuminations - Computing Pi
Curator: Sophia Borden
The applet shows 2 circles, each with an inscribed shape in blue and a circumscribed shape in red, one of the circles has a radius of 1 and the area of the inscribed and circumscribed shapes are given, the other circle has a diameter of 1 and the circumference of the inscribed and circumscribed shapes are given. The slider on the bottom increased the number of sides of the both the circumscribed and inscribed polygons and the area and circumference of the polygons will approach pi.
Grade Level: 7-12
PSSM Content Standard: Analyze characteristics and properties of two- and three- dimensional geometric shapes and develop mathematical arguments about geometric relationships.
CCSSM Content Standard: Know the formulas for the area and circumference of a circle and use them to solve problems; give an informal derivation of the relationship between the circumference and area of a circle.
Math Content: geometry, area, circumference, pi, limits
