## FAQs on RS Aggarwal Solutions Class 8 Chapter-24 Pie Charts (Ex 24A) Exercise 24.1

**1. Is RS Aggarwal for Class 8 Mathematics useful?**

The derivations and numerical components must be understood and practised, which is where Vedantu RS Aggarwal Mathematics solutions can help. The NCERT textbook can be used to cover the theory portion of the concept, which is an important aspect of the concept. Students benefit greatly from Vedantu's study material in terms of improving their understanding of the topics. Students should first go to the Vedantu official website, log in with their mobile number and email address, and then navigate to the grade 8 Mathematics page to download it.

**2. How can I do well in Class 8 Maths?**

The only way to do well in Class 8 Maths is to practice. Complete all of the Chapter Exercises. This will enhance your problem-solving abilities as well as your speed and efficiency. Important formulas, definitions, and equations can be written down in a notebook and reviewed on a regular basis. Solve previous year's sample papers and question papers within a time limit. This will familiarise you with the paper pattern and question type, as well as help you improve your time management skills. Revise on a regular basis to ensure that you retain everything you've learned for a longer period of time.

**3. How do you calculate the total number of data points in a Pie Chart slice? What are some Pie Chart Examples?**

To calculate the total number of data points in a slice of a Pie Chart, multiply the slice percentage by the total number of data points and divide by 100.

A slice of the Pie Chart, for Example, is equal to 60%, and the Pie Chart contains a total data set of 150. The value of 60% of a pie slice is then (60150)/100 = 90.

There are numerous real-world Examples of Pie Charts, including:

Students' grades in a Class are represented as a graph.

A representation of the various types of cars sold in a given month.

To demonstrate the type of food preferred by the people in a room.

**4. Why do we employ Pie Charts?**

Pie Charts are used to display proportional or relative data in a single graph. The concept of pie slices is used to demonstrate the percentage of specific data from the entire pie. Pie Charts have a fairly narrow use case that is particularly well encapsulated by their definition. To use a Pie Chart, you must have a whole amount that has been divided into a number of distinct parts. In a Pie Chart, your primary goal should be to compare each group's contribution to the whole, rather than comparing groups to each other. If the above criteria are not met, the Pie Chart is inapplicable, and a different plot type should be used instead.

**5. How do you produce a Pie-Chart?**

**Step 1:** Enter all of the information into a table and total the values.

**Step 2: **To calculate the percentages, divide each value by the total and multiply by 100.

**Step 3: **To calculate the number of degrees required for each pie sector, we take a full 360° circle and use the formula: (Frequency/Total Frequency) 360°

**Step 4: **After calculating all of the degrees for making a Pie Chart, use a protractor to draw a circle (Pie Chart) using the calculated measurements.
