CPM Homework Help : MC2 Problem 6-16

A class surveyed how students at their school travel to school. The results of the survey are shown in the table below. Make a circle graph showing the results of the survey using percentages.

Mode of Transportation	Number of Students
Bus	$90$
Ride Bike	$30$
Ride in Car	$75$
Walk	$45$

Hint:

Find the students using each mode of transportation as a percentage of all the students.

More Help 1:

Each category of data is then represented by a portion of the circle. The measure of the angle of each sector portion is directly proportional to the corresponding percentage.

More Help 2:

Consider the bike riders.
$\frac{30}{240}=0.125$ of the students population ride bikes to school.
Proportionately as an angle, this would be $12.5\%$ of $360°$ (a whole circle). This equates to $0.125(360°)=45°$ .
