In a pie chart, if the segment for transportation is 45 degrees, what percentage of the total does it represent? (2023)

Step 1: Understand that a pie chart is a circle that represents 360 degrees in total.
Step 2: Identify the angle of the segment for transportation, which is 45 degrees.
Step 3: To find the percentage, divide the angle of the segment (45 degrees) by the total degrees in a circle (360 degrees).
Step 4: Calculate the fraction: 45 divided by 360, which is 45/360.
Step 5: Convert the fraction to a percentage by multiplying by 100: (45/360) * 100.
Step 6: Perform the calculation: 45 divided by 360 equals 0.125, and then 0.125 multiplied by 100 equals 12.5.
Step 7: Conclude that the segment for transportation represents 12.5% of the total pie chart.
