How to Find the Area of a Sector

This is a math lesson from Magoosh on how to find the area of a sector. In this video, we use a helpful example about pizza in order to illustrate how finding the area of a sector works! :)

Before we tackle the pizza problems, we go over are some basic concepts that you need to know. The formula for the area of a circle is A = πr².
