Question

When you are making a circle graph by hand, how do you convert a number for a part into its corresponding angle measure in the circle graph?

Answer 1

Answer:

Multiply the quotient of the number and the total by 360 degrees.

Step-by-step explanation:

If there are three parts that you want to convert to a circle graph (say 12, 9 and 15)

Step 1: Add all the numbers together.

12+9+15 =36

Step 2: Multiply the quotient of each number and the total by 360 degrees.

These are:

$\dfrac{12}{36}\times 360^\circ = 120^\circ\\\dfrac{9}{36}\times 360^\circ = 90^\circ\\\dfrac{15}{36}\times 360^\circ = 150^\circ$

This is how you convert a number for a part into its corresponding angle measure.
