Calculate the sector angle on a pie chart for a given group A class of students were surveyed about how many siblings they have.

A selection of results are shown in the table. \begin{tabular}{|c|c|c|}
\hline Number of siblings & Frequency & Angle on a pie chart \\
\hline  0  & \( 7 \) & \( \bigstar \) \\
\hline 1  & \( \) & \( 144 \degree \) \\
\hline 2  & \(  \) & \(  \) \\
\hline 3  & \( 4 \) & \(  \) \\
\hline 4 or more  & \(  \) & \(  \) \\
\hline  TOTAL  & 30  & \(  \) \\
\end{tabular} Jenny wants to draw a pie chart of the information.

Which of the following calculations would work out what replaces the star? \( \frac{30}{360} \times 7 \)

Believes that to find an angle for a pie chart sector you divide the total frequency by 360 and multiply by its frequency
