A pie chart is a circle used to represent information. A complete circle is 360o, this is divided into portions with respect to the degrees.
Ex: Mr. Jong divided his money as follows;
Food = 60% car allowance = 20% rents = 10% saving = 10%
Using a pie chart, illustrate the following information
Solution:
Sum of percentages = 60+20+10+10 = 100% = 360o
Food = 60/100 * 360 = 216o
Car allowance = 20/100 * 360 = 72o
Rents = 10/100 * 360 = 36o
Savings = 10/100 * 360 = 36o
