What did you come up with for the Warm-Up problem? Did you get 13 square units? I hope not, because that would be wrong. Duration: 7:23

This brief video introduces the lesson goal and defines composite figures as something associated with interesting architecture, apparently. Duration: 2:15

Let's debrief on Example 1, examining a few different strategies that you can use to find the area and the perimeter of a composite figure. Duration: 8:40

Example 3 demonstrates that not all SAT questions are as difficult as we may have been lead to believe, while Example 4 introduces curved edges to our composite figures. Duration: 8:06

The second half of Example 4 tasks us with finding the area of composite figures, again involving curved edges. Along the way, we'll have to find the area of an equilateral triangle. Duration: 13:17

Up until this point, we have managed to conduct mathematics without the use of pizza. That needs to stop. In doing so, we'll introduce the terms central angle, arc measure, and arc length. Duration: 10:52

Example 7 puts those arc length formulae to good use. Duration: 3:37

While we associate arc length with the crust on a piece of pizza, the actual slice of pizza with its stringy cheese and fresh toppings is a sector. Here, we will learn to find the area of such a shape. Duration: 11:33
