A pie chart illustrates the time spent by students on various subjects. If 15% of the time is spent on Mathematics, what is the angle in degrees representing this portion of the pie chart?
54 degrees
36 degrees
27 degrees
45 degrees
To find the angle, multiply the percentage by 360 degrees: 15% of 360 = 0.15 * 360 = 54 degrees.

Q: A pie chart illustrates the time spent by students on various subjects. If 15% of the time is spent on Mathematics, what is the angle in degrees representing this portion of the pie chart?
Solution: To find the angle, multiply the percentage by 360 degrees: 15% of 360 = 0.15 * 360 = 54 degrees.
Steps: 5
Step 1: Understand that a pie chart represents a whole circle, which is 360 degrees.
Step 2: Identify the percentage of time spent on Mathematics, which is 15%.
Step 3: Convert the percentage to a decimal by dividing by 100: 15% = 15 / 100 = 0.15.
Step 4: Multiply the decimal by 360 degrees to find the angle: 0.15 * 360 = 54 degrees.
Step 5: Conclude that the angle representing the time spent on Mathematics in the pie chart is 54 degrees.
