Unit 8: Circles
Circles are everywhere you look, for example, tires, pools, fans, and watches. You can probably think of several more items that are circular. In this unit, you will learn about circles and arcs, which are slices of the edge of a circle.
Believe it or not, arcs are used a lot in real life. The feet of a rocking chair are arcs; the crust on a slice of pizza is an arc. Anything that looks like an incomplete circle is an arc. How are these arcs made? What kinds are there? How can we measure them? These are questions that you will explore in this unit.
Completing this unit should take you approximately 16 hours.
