Study the graph and find the angle of sector of coffee.
To determine the angle of the sector representing coffee in the given pie chart, we use the concept that the entire circle of the pie chart represents 360°. The percentage of each sector can be used to find its corresponding angle.
From the image, we observe the following information for the sectors:
To find the angle for the coffee sector, we use the formula:
\(\text{Angle of sector} = \left( \frac{\text{Percentage of total}}{100} \right) \times 360^\circ\)
Substituting the value for coffee:
\(\text{Angle of coffee} = \left( \frac{20}{100} \right) \times 360^\circ = 72^\circ\)
Thus, the angle of the sector representing coffee is 72°.
This calculation matches the correct answer provided in the options, which is 72°.
