What is the total percent represented in a circle graph?

Back

The total percent represented in a circle graph is always 100%.

How do you calculate the percentage of a category in a circle graph?

Back

To calculate the percentage of a category, divide the part by the total and multiply by 100.

Front

If a circle graph shows 30% for one category, what does this mean?

Back

This means that the category represents 30 out of every 100 parts of the total.

Front

What is the purpose of using a circle graph?

Back

It represents 90 degrees, since 25% of 360 degrees (the total degrees in a circle) is 90 degrees.

What is a key advantage of using circle graphs?

Back

A key advantage of using circle graphs is that they provide a clear visual representation of data proportions.
