Question

You asked your classmates to name their favorite type of music. You found that 12 students like rock, 8 like rap, 6 like R&B, and 4 like jazz. Suppose you made a pie chart to display the data. How many degrees of the circle should represent rock music?

Answer 1

From this, we can see that the total amount of students being asked = 12 + 8 + 6 + 4 = 30.

12 of 30 like rock, in percentages that is 12/30 = 40$

Full circle has 360 degrees.

40% * 360 degrees = 144 degrees

144 degrees should represent rock music on a pie chart.

Hope this helps!
