Answer:
here's ur answer dude
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. While it is named for its resemblance to a pie which has been sliced, there are variations on the way it can be presented. The earliest known pie chart is generally credited to William Playfair's Statistical Breviary of 1801.

Answer:
It is also known as angular diagram. Pie diagrams are more popularly used for presenting percentage breakdown of data. For example, students of a particular college may be put in three categories-Science students, Commerce students and Arts students.
The pie diagram can be effectively used to show these categories or breakdowns. A pie diagram therefore, is a circle subdivided into component sectors to present the proportion of different constituent parts to the total. As such a pie diagram is shown in percentage terms.
Explanation:
Steps in the construction of pie diagram
Step 1. Find the value of each category or component or group as percentage of total of all categories or components or groups.
Step 2. Calculate degree of the angle formed by each category or component or group by the formula given below.
Degree for a particular category/component/group
=
Value of the group 360
Total of all groups

Step 3. Take a circle of a suitable size and draw radius.
Step 4. Now draw angles calculated in step 2 with the help of a protractor.
Step 5. Shade or colour different segments suitably or make the distinctions between different categories or components or groups.
Step 6. For each category or component or group put the percentage in the pie diagram.
