Calculate 40% of the central angle of a pie chart

Answer:
In any sector, there are 3 parts to be considered:
the arc length,
the sector area
the sector angle
They all represent the SAME fraction of the whole circle.
The arc length is a fraction of the circumference
The sector area is a fraction of the whole area
The sector angle is a fraction of 360°
If the sector is 20% of the pie chart, then each of these parts is 20% of the whole.
The sector angle is therefore:
20%×360°
20100×360=72°
