Question 1 Report
Use this information about a pie chart to answer the question. The pie chart shows how \(72\) students travel to school. The angle of the sector for walking is \(150^\circ\). Work out how many students walk. Then calculate the angle that stands for \(12\) students. The pie chart in the diagram shows the sector for walking.
Answer Details
A full pie chart is \(360^\circ\) and represents all \(72\) students.
The walking sector represents \(\frac{150}{360}\) of the students:
\[\frac{150}{360}\times72=30\]
So \(30\) students walk [M1][A1].
Each student represents \(360\div72=5^\circ\). Therefore, for \(12\) students:
\[12\times5^\circ=60^\circ\]
The required angle is \(60^\circ\) [B1].
