Question
The owner of a paper company examined last year's production. 45% of the paper produced was graph paper. If this information is displayed in a circle graph, what is the measure of the central angle in the "Graph paper" section?°Submit
Solution
To find the measure of the central angle for the "Graph paper" section of the circle graph, you need to know that a circle graph (or pie chart) represents 100% of the data and that a full circle has 360 degrees.
Here are the steps to calculate the central angle:
-
Convert the percentage of graph paper produced into a decimal. You do this by dividing the percentage by 100. So, 45% becomes 0.45.
-
Multiply this decimal by the total degrees in a circle. So, 0.45 x 360 = 162.
Therefore, the measure of the central angle in the "Graph paper" section is 162 degrees.
