You can easily make a pie chart in Excel to make data easier to understand. The process only takes 5 steps.

Sure, you can cut a pie into pieces, but what if it’s in four dimensions? Using spectral graph theory, mathematicians have solved a decades-old problem. Graph theory uses nodes and edges (dots and ...

Pie charts are a way to show data. Pie charts show proportions of a whole. The circle of the pie chart represents the whole. That's a full 360 degrees. Each part, or slice, represents part of the ...

WASHINGTON (7News) — It's Friday, March 14 —3/14, the day that every math nerd eagerly anticipates each year. Known around the world as "Pi Day," it’s a time to celebrate one of mathematics' most ...

Using spectral graph theory, mathematicians have solved a decades-old problem. Graph theory uses nodes and edges (dots and lines) to represent data. If you’ve ever drooled over a cherry pie, cut into ...

A pie chart can show collected data in sectors. Each sector can be labelled, or can be colour coded with a key. When drawing a pie chart, a protractor will be used to draw the angles accurately. Being ...
