Question

The pie chart is divided into:
(A) sectors
(B) circles
(C) squares
(D) segments

Answer 1

Hint: A pie chart is a type of graph used to represent data. It is a type of pictorial representation of data. As the name suggests, the term ‘pie’ represents a whole and the slices in the pie chart represent the respective parts of a whole. We shall now discuss the construction of a pie chart and how it is used to represent a data set. This will give us the answer to our problem.

Complete step by step solution:
A pie chart is one of the most important pictorial form of data representation. It contains different parts also called pie in a pie chart. Each part forms a certain portion of the total percentage. The sum of all the parts is ${{360}^{\circ }}$. And the total value of a pie is constant and always 100%.
A pie chart as the name suggest is in the shape of a pie, that is, it is a circle in which all the different parts that make up some angle at the center of the circle are called sectors.
A pie chart is constructed by allotting the degree of a sector (say d) of a certain value as:
$\Rightarrow d=\left( \dfrac{\text{the value of data}}{\text{the sum of all the data}} \right)\times {{360}^{\circ }}$
For example, the sales pie chart of a certain business in its four quarters can be represented as a pie chart with the help of following diagram:

Thus, from our above definition, we can see that a pie chart is divided into sectors.

So, the correct answer is “Option A”.

Note: The pie chart is extensively used to represent data in a business firm. It is used to compare the growth areas such as business profits, turnover, exposure, etc. Another very important characteristic of a pie chart is that it gives us a data comparison at just a glance while simultaneously giving us the accurate data of different variables visually.
