Calculating Percentages of Angles

The video tutorial explains how to calculate the number of degrees that correspond to a given percentage of a circle or pie chart. It starts by stating that a circle has 360 degrees. To find a specific percentage of the circle, you multiply the percentage (converted to a decimal) by 360. For example, 35% of a circle is 126 degrees. The tutorial provides additional examples, such as 30% being 108 degrees, 15% being 54 degrees, 133% being 46.8 degrees, and 7% being 25.2 degrees.
