"Which of the following math teachers would you recommend for the 'Teacher of the Year Award'?"

Mr. Brain
Mr. Knowitall
Ms. Calculus
Ms. Imneverwrong

The following table shows the results

Teacher How many voted for this teacher Fraction of those who voted for this teacher Percentage of those who voted for this teacher Measurement of central angle
Mr. Brian 67 67/400 16.75%
Mr. Knowitall 89 89/400 22.25%
Ms. Calculus 161 161/400 40.25%
Ms. Imneverwrong 83 83/400 20.25%
Total (Verfication) 400


Note: Totaling each column will verify your calculations.


  1. Using a protractor construct a circle graph by using some of the skills you have learned from geometry and the information from the above table. (Hint: You will need to convert the percent who voted for each teacher into a fraction of 360º).

Section B

  1. At a local music store, 250 people were surveyed about their favourite Canadian artist. The table below shows the results. Complete the table and then construct a circle graph by hand to display the data.
