# Pie Charts Flashcards

1️⃣ Familiarise yourself with the flashcards:

• Look through all the flashcards to see what’s on both sides.
• Make sure you understand the information on each card. If something’s unclear, click the link to the revision notes at the bottom of the page for more details.

2️⃣ Test yourself:

• Look at the question or prompt on each card and try to remember the answer before flipping it over.
• Check the answer and make a note of any cards you find challenging and need to go over more.

3️⃣ Consistently Review and Practice:

• Use spaced repetition: spend more time on the cards you struggle with and go over them more often.
• Regularly review all the flashcards to help you better understand and retain the information over time.

Note: We may include questions that have multiple correct answers. It’s useful to remember specific examples to understand these concepts better.

## What does a pie chart show?

A pie chart shows proportions within a circle, divided into segments, making it highly effective for visual comparisons.

## How do you calculate the percentage for a pie chart segment?

To calculate the percentage for a segment: divide the category value by the total value and multiply by 100.

## How do you convert percentages into degrees for a pie chart?

To convert percentages into degrees: multiply the percentage by 360 (since a circle totals 360 degrees).

## What is the formula to calculate the degrees for a pie chart segment?

The formula is:
(Category value ÷ Total value) × 360

## Calculate the degrees for a pie chart segment if the percentage is 15%.

15% of 360 degrees is (0.15 × 360) = 54 degrees.

## How do you draw segments in a pie chart?

First, draw a circle using a compass, then use a protractor to draw each segment based on the calculated degrees for each category.
