Start with the fact that the entire circle represents 100% of the total budget, which corresponds to 360 degrees in a circle.
To find the number of degrees for 20% of the budget, you can set up a proportion:
(20% of the budget) is to (360 degrees) as (x degrees) is to 360 degrees.
So, (20/100) = (x/360).
- Now, solve for x:
x = (20/100) * 360
x = (1/5) * 360
x = 72 degrees
So, 20% of the total budget should be represented by 72 degrees on the circle graph.
