Question

In a pie chart, the total angle at the center of the circle is

• A. $180°$
• B. $360°$
• C. $270°$
• D. $90°$

Answer 1

The correct option is B

$360°$

Explanation for the correct option:

1. Pie chart is similar to a circle.
2. Pie chart uses sectors to represent the data.
3. Each sector's area is directly proportional to the population size of the class of data it represents.
4. The angles of the sectors sum up to $360°$.
5. Thus, angle subtended by the pie chart is $360°$, similar to a circle.

Hence Option B is the correct answer.
