Question

Name the type of graph in which central angle is involved.​

Answer 1

Step-by-step 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°

20/100×360=72°
