After going over our homework, we took at look at our lesson that involved arc lengths and sector areas. We used the circle formulas for area and circumference again, and combined them with determining the fraction of a circle in order to figure out several different types of problems. We worked on creating a fraction using the central angle divided by 360 to determine both arc lengths and sector areas. We also did a few problems in which the central angle needed to be calculated. The students then got started on their assignment.
