1. Problem Description

The table shows the number of times each meal (Burger, Pasta, and Soup) was ordered at a restaurant. We are asked to find the central angle (in degrees) of the section that represents soup in a pie chart displaying this information.

2. Solution Steps

First, we need to find the total number of meals ordered.
Total number of meals = Number of Burgers + Number of Pastas + Number of Soups
Total=17+4+9=30Total = 17 + 4 + 9 = 30
Next, we need to find the fraction of meals that are soup.
Fraction of soup = NumberofSoupsTotalnumberofmeals\frac{Number of Soups}{Total number of meals}
Fraction of soup = 930\frac{9}{30}
Now, we need to find the central angle for the soup section in the pie chart. A full circle has 360 degrees.
Central angle of soup section = Fraction of soup ×\times 360 degrees
Central angle of soup section = 930×360\frac{9}{30} \times 360
Simplify the fraction: 930=310\frac{9}{30} = \frac{3}{10}
Now, calculate the angle:
Central angle of soup section = 310×360\frac{3}{10} \times 360
Central angle of soup section = 3×36=1083 \times 36 = 108 degrees.

3. Final Answer

The central angle of the section that represents soup should be 108 degrees.
