Chipwich Summer Camp surveyed 100 campers to determine which lake activity was their favorite. The results are given in the table below.

| Lake Activity | Number of Campers |
|----------------|--------------------|
| Kayaking | 15 |
| Wakeboarding | 11 |
| Windsurfing | 7 |
| Waterskiing | 13 |
| Paddleboarding | 54 |

If a circle graph was constructed from the results, which lake activity has a central angle of [tex]\(54^{\circ}\)[/tex]?

A. Kayaking
B. Wakeboarding
C. Waterskiing
D. Paddleboarding



Answer :

To determine which lake activity corresponds to a central angle of [tex]\(54^{\circ}\)[/tex] in a circle graph (or pie chart), we need to follow these steps:

1. Understand the connection between degrees and the percentage of the total circle:
- A circle has a total of 360 degrees.
- Each degree represents [tex]\(\frac{1}{360}\)[/tex] of the total circle, or about [tex]\(0.278\%\)[/tex].

2. Determine what percentage [tex]\(54^{\circ}\)[/tex] represents of the entire circle:
- Since the entire circle is 360 degrees, we calculate the percentage of the circle represented by [tex]\(54^{\circ}\)[/tex] as follows:
[tex]\[ \text{Percentage} = \left(\frac{54}{360}\right) \times 100 \][/tex]

3. Calculate this percentage:
- [tex]\(\frac{54}{360} = 0.15\)[/tex]
- [tex]\(0.15 \times 100 = 15\%\)[/tex]

4. Calculate the number of campers represented by this percentage:
- The survey includes a total of 100 campers.
- Thus, [tex]\(15\%\)[/tex] of 100 campers is:
[tex]\[ 0.15 \times 100 = 15 \text{ campers} \][/tex]

5. Identify which lake activity corresponds to the number of campers (15 campers):
- According to the table, Kayaking has 15 campers.

So, the lake activity that corresponds to a central angle of [tex]\(54^{\circ}\)[/tex] on the circle graph is Kayaking.
