Questions & Step-by-Step Solutions

A pie chart illustrates the time spent by students on various subjects. If Mathematics takes up 25% of the time, what is the angle in degrees representing Mathematics on the pie chart?
  • Step 1: Understand that a pie chart represents a whole circle, which is 360 degrees.
  • Step 2: Know that the percentage of time spent on Mathematics is 25%.
  • Step 3: Convert the percentage to a fraction: 25% is the same as 25 out of 100, or 25/100.
  • Step 4: To find the angle for Mathematics, multiply the fraction (25/100) by the total degrees in a circle (360 degrees).
  • Step 5: Calculate the angle: (25/100) * 360 = 90 degrees.
  • Percentage to Angle Conversion – Understanding how to convert a percentage of a whole into an angle in a pie chart.
