Problema Solution
Manuel surveyed people to find out where they liked to read. He constructed a circle graph of the data. The central angle for the portion of the graph that represents "next to the fireplace" measures 84°. If 21 people chose "next to the fireplace," how many people were surveyed?
Answer provided by our tutors
number of people = 21
angle = 84 degrees
we get
84/360 *x = 21
x = 21*360/84
x = 90
total 90 were surveyed
