Question

what is the angle subtended at the center of pie chart​

Answer 1

Step-by-step explanation:

In a pie chart, the various observations or components are represented by the sectors of a circle and the whole circle represents the sum of the values of all components. The central angle for a component is given by: Central angle for a component = Value of the componentSum of the values of all components × 360°

In any sector, there are 3 parts to be considered:

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.

20%×360°

20100×360=72°

Answer 2

Answer:

79.2 °
