To solve this problem, we need to calculate the central angle for the "Printer paper" section of the pie chart. The total central angle of a circle is 360°, and the percentage allocated to the "Printer paper" section is 15%.

The formula for calculating the central angle is:

$\text{Central angle} = \text{Percentage} \times 360^\circ$

Substituting the given percentage:

$\text{Central angle} = 15\% \times 360^\circ = 0.15 \times 360^\circ = 54^\circ$

Thus, the central angle for the "Printer paper" section is 54°.

Tip: Always check that the sum of all central angles in a pie chart equals 360° to ensure accuracy!
