What is a circle graph?

Back

A circle graph, also known as a pie chart, is a circular statistical graphic divided into slices to illustrate numerical proportions.

How do you calculate the percentage of a part compared to the whole?

Back

To calculate the percentage, divide the part by the whole and then multiply by 100. For example, (part/whole) x 100.

What does 30% of 250 represent in a circle graph?

Back

It represents a segment of the circle that corresponds to 30% of the total value, which is 75.

Front

How do you convert a fraction to a percentage?

Back

To convert a fraction to a percentage, divide the numerator by the denominator and multiply by 100. For example, 1/4 = (1 ÷ 4) x 100 = 25%.

What is the relationship between fractions and percentages in circle graphs?

Back

Fractions can be converted to percentages to show how much of the whole each part represents in a circle graph.

Front

How can you find the total from a percentage?

Back

To find the total from a percentage, divide the part by the percentage (in decimal form). For example, if 75 is 30%, then total = 75 / 0.30 = 250.

What does a slice in a circle graph represent?

Back

A slice in a circle graph represents a part of the whole, showing the proportion of that part relative to the total.

Front

How do you read a circle graph?

Back

To read a circle graph, look at the size of each slice to understand the proportion of each category compared to the whole.

Front

What is the purpose of using a circle graph?

Back

The purpose of using a circle graph is to visually represent data and make it easier to compare parts of a whole.

How do you determine which graph matches a table of values?

Back

To determine which graph matches a table of values, compare the numerical data in the table to the sizes of the slices in the graph.
