## What does a circle graph looks like?

A circle graph is also known as a pie chart. The graph is in the shape of a circle with different wedges that each represent a percentage of a total. These wedges often look like pieces of pie, which is why the circle graph is sometimes referred to as a pie chart.

## What do you see in a circle graph?

A circle graph, or a pie chart, is used to visualize information and data. A circle graph is usually used to easily show the results of an investigation in a proportional manner. The arcs of a circle graph are proportional to how many percent of population gave a certain answer.

**What percentage does a whole circle graph represent?**

100%

Circle Graph. A circle graph is a visual representation of data, made by dividing a circle into sectors that each represent parts of a whole. Usually the amounts in each sector are represented in percent, so that all of the amounts total 100%.

**What is the total percent of a pie or circle graph?**

This ratio works because the total percent of the pie chart represents 100% and there are 360 degrees in a circle. Therefore 47.1 degrees of the circle (13.1%) represents the time spent eating lunch.

### What is general equation of circle?

We know that the general equation for a circle is ( x – h )^2 + ( y – k )^2 = r^2, where ( h, k ) is the center and r is the radius.

### When should you not use a circle graph?

Don’t use a circle graph when you have similar data values. A pie chart is not suitable for times when the difference between your data entries is minimal. For instance, the data reads 23%, 25%, and 26%. When you plot them on a circle graph, the slices representing each value would be similar in size.

**How do you find the degree of a circle?**

Use 3.14159 to represent pi. Plug radians into the formula to find the degrees. For example, if you have pi radians, plug pi into your formula: pi = degrees * pi/180, so degrees = 180.

**How many sector are in the circle graph?**

Circle graphs are popular because they provide a visual presentation of the whole and its parts. However, they are best used for displaying data when there are no more than 5 or 6 sectors and when the values of each section are different.

## What do you notice about a circle?

A circle is a round shaped figure that has no corners or edges. In geometry, a circle can be defined as a closed, two-dimensional curved shape.

## What does an empty circle mean on a graph?

Correct answer: An open circle indictes “less than” or “greater than,” while a closed circle indicates “greater than or equal to” or “less than or equal to”. This number line includes values that are less than or greater than or equal to .
