Question

Last week, there were 450 student absences at Johnson High. The circle graph below summarizes them by the day of the week on which they occured.
The central angle for the Tuesday slice is 57.6°. What percentage of the absences occured on Tuesday? Do not round.

Answer 1

Answer:

Percentage of absentees on Tuesday = 16%

Step-by-step explanation:

Sum of all central angles representing days = 360°

Central angle of the sector representing Tuesday = 57.6°

Therefore, percentage absentees on Tuesday

= $\frac{\text{Measure of central angle for Tuesday}}{\text{Sum of all central angles}}\times 100$

= $\frac{57.6}{360}\times 100$

= 16%

Percentage of absentees on Tuesday = 16%
