Answer 1

Answer:

please mark this as brain list answer.......

Step-by-step explanation:

A pie chart can used to compare the relation between the whole and its components. A pie chart is a circular diagram and the area of the sector of a circle is used in a pie chart. Circles are drawn with radii proportional to the square root of the quantities because the area of a circle is πr2.

To construct a pie chart (sector diagram), we draw a circle with radius (square root of the total). The total angle of the circle is 360∘. The angles of each component are calculated by the formula.

AngleofSector=Component PartTotal×360∘

These angles are made in the circle by means of a protractor to show different components. The arrangement of the sectors is usually anti-clock wise.
