Question: 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?

Options:

  1. 54 degrees
  2. 36 degrees
  3. 27 degrees
  4. 45 degrees

Correct Answer: 54 degrees

Solution: 

To find the angle, multiply the percentage by 360 degrees: 15% of 360 = 0.15 * 360 = 54 degrees.

Questions & Step-by-Step Solutions

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?
  • 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.
  • Percentage to Angle Conversion – Understanding how to convert a percentage of a whole into an angle in a pie chart by using the formula: angle = (percentage/100) * 360.
