Finding the Area of a Circle

The video tutorial explains how to find the area of a circle by relating it to the area of a rectangle. It reviews the calculation of rectangle area and the concept of squaring numbers. The importance of the order of operations is highlighted, particularly the precedence of exponents over multiplication. The tutorial uses a pizza to visualize the circle's area, demonstrating how slices can form a rectangle. The formula for the area of a circle, πr², is derived and applied in examples, emphasizing the use of radius over diameter and the correct order of operations.
