Billions of federal dollars are often distributed to states and communities for a variety of projects.
Let’s Create a pie graph to accurately display this data

The table to the left shows billions of dollars and percentages of the total Federal Aid Budget for several categories of spending

Do this by converting the percentage into a decimal and multiplying the decimal by 360

Next, lay your protractor over the midpoint of the circle on your worksheet as shown.
Measure 19° from the bottom of the circle (180°) and mark this point along the circle.
