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.

How do you tell if a graph is a circle?
The simplest circle to graph is one whose center is at the origin (0, 0). Because both h and v are zero, they can disappear and you can simplify the standard circle equation to look like x2 + y2 = r2.
What does a circle in a graph mean?
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%. Circle Graph Example.
What type of data does a circle graph show?
A pie chart, sometimes called a circle chart, is a way of summarizing a set of nominal data or displaying the different values of a given variable (e.g. percentage distribution). This type of chart is a circle divided into a series of segments.
How do you identify if the graph of an equation is a circle or a point?
Formula of a Circle
To find out if an equation is that of a circle, there are four important things to remember. The first is that the x and y terms are squared. The second is all terms in the equation are positive. The third is the center point of the circle is (h,k).
What is a circle graph kids?
A circle graph is a graph in the shape of a circle that shows different parts. Each part of a circle graph represents a different category. You can use a circle graph to visually compare the parts to the whole, and the parts to each other. A larger part means that the category represented by that part is more common.
Is a circle graph a function?
A circle is a curve. It can be generated by functions, but it’s not a function itself. Something to careful about is that defining a circle with a relation from x to y is NOT a function as there is multiple points with a given x-value, but it can be defined with a function parametrically.
How do you make a circle graph on Excel?
Excel
- In your spreadsheet, select the data to use for your pie chart.
- Click Insert > Insert Pie or Doughnut Chart, and then pick the chart you want.
- Click the chart and then click the icons next to the chart to add finishing touches:
What data is best displayed on a circle graph?
Circle graphs are best used for displaying data when there are no more than five or six sectors, and when the values of each sector are different. Otherwise they can be difficult to read and understand.
What bar graphs look like?
A bar chart is a graph with rectangular bars. The graph usually compares different categories. Although the graphs can be plotted vertically (bars standing up) or horizontally (bars laying flat from left to right), the most usual type of bar graph is vertical.
What is circle graph in data handling?
A circle graph or pie chart shows the relationship between a whole and its parts. A circle is divided in sectors. Size of each sector is proportional to the activity or information it represents.
How do you find the equation of a 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.
Is a pie chart and a circle graph the same?
A pie chart (or a circle chart) is a circular statistical graphic, which is divided into slices to illustrate numerical proportion. In a pie chart, the arc length of each slice (and consequently its central angle and area), is proportional to the quantity it represents.
What are line graphs used for?
Line graphs are used to track changes over short and long periods of time. When smaller changes exist, line graphs are better to use than bar graphs. Line graphs can also be used to compare changes over the same period of time for more than one group.
What is a graph in kindergarten?
Graphs show you information as a visual image or picture. We can call this information ‘data. ‘ There are many different types of graphs. Bar graphs help you compare different data set to one another. Line graphs have little dots to represent the information and a line connecting them to show what happens to the data.
What does a picture graph look like?
Definition of a Picture Graph
A picture graph is a pictorial display of data with symbols, icons, and pictures to represent different quantities. The symbols, icons, and pictures of a picture graph typically represent concepts or ideas, or stand in for a larger quantity of something.
Is a circle one to many?
A relation can also be one to manyor many to many– where x values can have more than one y value. A circle is an example of this of a many to many function. A vertical line can cut through this graph more than once.
How do you read a math graph?
The line along the bottom is called the horizontal or x-axis, and the line up the side is called the vertical or y-axis.
- The x-axis may contain categories or numbers. You read it from the bottom left of the graph.
- The y-axis usually contains numbers, again starting from the bottom left of the graph.
How do you make a graph in math?

- Click to see a step-by-step slideshow.
- YOU WILL NEED: A whiteboard.
- STEP 1 – Draw a table of values for the x and y coordinates.
- STEP 2 – Using the equation y = 2x + 1, calculate the value of y by using the x value in the table.
- STEP 3 – Draw a graph and label the x axis 1 to 4 and the y axis 1 to 9.
