Question

In a pie chart, size of each sector is proportional to the value of item represented by it.

( Write true or false).​

Answer 1

Step-by-step explanation:

A pie chart (or a circle chart) is a circular statistical graphic, which is divided into slices to illustrate numerical proportion. In a pie chart, the arc length of each slice (and consequently its central angle and area), is proportional to the quantity it represents.

To calculate the percentage each slice is worth, measure the angle of each slice and divide this by 360 then multiply it by 100. To find the number of pieces of data each slice represents, multiply the percentage that each slice is worth by the total number of the data sets.
