This lesson is all about pie, or should I say, pi. Cherry's my favorite. What about yours?
Geometry 11(B) determine the area of composite two-dimensional figures comprised of a combination of triangles, parallelograms, trapezoids, kites, regular polygons, or sectors of circles to solve problems using appropriate units of measure
Geometry 12(B) apply the proportional relationship between the measure of an arc length of a circle and the circumference of the circle to solve problems;
Geometry 12(C) apply the proportional relationship between the measure of the area of a sector of a circle and the area of the circle to solve problems;
Geometry 12(D) describe radian measure of an angle as the ratio of the length of an arc intercepted by a central angle and the radius of the circle
