Circle Graph Formula

About Circle Graph Formula

A circle graph is the intersection graph of a set of circle chords in graph theory. It's an undirected graph whose vertices can be linked-to circle chords, with two vertices being adjacent if and only if the corresponding chords cross. A pie graph or pie chart is another name for a circle graph.

The following are some essential circle graph formulas:

  1. Percentages = (Amount in the Category ⁄ Total) × 100
  2. Angle = (Amount in the Category ⁄ Total) × 360°

Example: 36 percent apples, 29 percent bananas, 9 percent mangoes, 7 percent pineapples, and 19 percent grapes make up a fruit basket. Make a circle graph chart using the information supplied.

  1. Sol:Given that,
  2. Apples – 36%
  3. Bananas –29%
  4. Mangoes –9%
  5. Pineapples –7%
  6. Grapes –19%

With the above data, the circle graph will be drawn as:

Example: The following information reveals the number of distinct mobile phones utilised by employees in one company department. Using angle proportions, create a circle chart with the following data.

Mobile phone Number of users
Apple phone 9
HTC 12
Samsung 6
Sony 8
Nokia 1

Sol:Angle = (Amount in the Category ⁄ Total) × 360°

Mobile phone Number of users Angle
Apple phone 9 (9/36) × 360° = 90°
HTC 12 (12/36) × 360° = 120°
Samsung 6 (6/36) × 360° = 60°
Sony 8 (8/36) × 360° = 80°
Nokia 1 (1/36) × 360° = 10°
