Read amounts, counts and percentages off a pie chart
Work out the angles and draw a pie chart ourselves
Find the mean, and find a missing value from it

The angle at the centre of a circle is 360°
That same 360° stands for the whole of the data
The angle of a heading is \( \theta = \frac{360^\circ}{T} \times V \)
The angles must always add back to 360°
