Step-by-step explanation:

For example-

20% of 360= 72

Explanation

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°
