Here, we will discuss pie charts and the sectors of a circle. We'll see how to convert frequencies to fractions, and convert those fractions to the corresponding degrees. After converting it to degrees, we will see how to draw a pie chart with degrees. Then we'll see how to convert a sector's degrees to a fraction, and how to use that fraction to find the percentage for a particular event. Then we'll see if that shows how to use this pie chart to find the total for a particular component.
