What is the 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 are the advantages of a circle graph?


  • display relative proportions of multiple classes of data.
  • size of the circle can be made proportional to the total quantity it represents.
  • summarize a large data set in visual form.
  • be visually simpler than other types of graphs.
  • permit a visual check of the reasonableness or accuracy of calculations.

What is a circular graph called?

A pie chart (or a circle chart) is a circular statistical graphic, which is divided into slices to illustrate numerical proportion.

What do circle graphs need?

A circle graph shows how the parts of something relate to the whole. A circle graph is divided into sectors, where each sector represents a particular category. The entire circle is 1 whole or 100%, and a sector of the circle is a part. Let’s define the various regions of a circle graph.

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.

What is a circle function called?

The circle below is drawn in a coordinate system where the circle’s center is at the origin and has a radius of 1. This circle is known as a unit circle. Since both the coordinates are defined by using a unit circle, they are often called circular functions. …

How do you graph a circle with radius and center?

Center away from the origin

  1. Locate the center of the circle from the equation (h, v). Place the center of the circle at (3, –1).
  2. Calculate the radius by solving for r.
  3. Plot the radius points on the coordinate plane.
  4. Connect the dots to the graph of the circle with a round, smooth curve.

How do you change the center of a circle?

The center-radius form of the circle equation is in the format (x – h)2 + (y – k)2 = r2, with the center being at the point (h, k) and the radius being “r”. This form of the equation is helpful, since you can easily find the center and the radius.

What does K represent in a circle?

The general equation of a circle is (x – h)2 + (y – k)2 = r2, where (h, k) represents the location of the circle’s center, and r represents the length of its radius.

How do you use a circle?

Pairing Circle with your router

  1. Place the Circle device near your router and plug it in.
  2. Begin Setup.
  3. Get updates & plug in the Circle device.
  4. Connect to the Circle device hotspot.
  5. Tell Circle your Wi-Fi network & password.
  6. Connect back to your home Wi-Fi.

How do you paint a perfect circle?

Paint in your stencil with a paintbrush or paint roller. Then, dip a 1 1⁄2 in (3.8 cm) angled paintbrush, foam paintbrush, or paint roller into the paint. Start painting from the outer edge of the stencil towards the middle of the circle. Then, paint across the center of the stencil to completely fill in your circle.

How do you remove the Perfect Circle tape?

Trace the circle on a piece of contact paper. The contact paper will take place of painter’s tape. Pull back about 1/3 of the paper backing. Starting along one edge, align the circle and pull the rest of the backing off as you smooth the contact paper down.

What do you use for dot painting?

Simply sharpen the eraser end of a couple pencils to different sized dots. You can also use the sharpened end of your pencil for your smallest size. Practice a bit on a piece of paper you will see that different amounts of pressure will make different sized circles.
