To find the measure of the central angle for the "Camping" section in the pie chart, you can use the following formula:

$\text{Central Angle} = \left(\frac{\text{Percentage of Total Revenue}}{100}\right) \times 360^\circ$

Given that 5% of the revenue came from camping equipment, the calculation would be:

$\text{Central Angle} = \left(\frac{5}{100}\right) \times 360^\circ = 0.05 \times 360^\circ = 18^\circ$

So, the central angle for the "Camping" section in the pie chart is 18 degrees.

Here are some related questions you might find helpful:

1. How would the central angle change if the percentage were 10%?
2. What would be the central angle for a category that makes up 25% of the revenue?
3. How can you determine the percentage of revenue if you only know the central angle?
4. If two categories each make up 15% of the revenue, what would be the sum of their central angles?
5. How would the pie chart look if one category made up 50% of the revenue?

Tip: Remember that the sum of all central angles in a pie chart is always 360 degrees, representing 100% of the data.
