500 people are asked to name their favorite color. The results of this survey are shown in the pie chart below:

Each sector of the pie chart makes an angle at the center. For example, the yellow sector makes an 18 angle, since 18 is 5% of 360.

A: Which sector makes an angle closest to 40? (Your answer should be a color word.)

 

B: If we consider only the people who named a rainbow color (red, orange, yellow, green, blue, or purple), what percentage of those people preferred red?

40/360 x 100% =11.1% ~~~~ Purple

 

R + O + Y +G + P = 13+4+5+15+16+12 = 65% of 500 people      13% / 65%  = 20 percent chose red
