{{ printedBook.courseTrack.name }} {{ printedBook.name }} A circle is defined as a set of points all with the same distance from a center point. This chapter will explore circle intersections, inscriptions, and measurements. We'll continue by introducing the special ratio between the circumference and diameter of a circle, $\pi$ (pi), and how to use it to calculate the circumference and area of a circle.
