The definition of pi gives us a way to calculate circumference. The circumference of a circle is the distance around a circle. If π = , then C = πd. You can also calculate the circumference of a circle with C = 2πr. The area of a circle is A = π. This learning progresses as students study cylinders, spheres, and cones.
