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?

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 a subject can be converted into an angle.
Step 3: For Mathematics, the percentage is 25%.
Step 4: To find the angle, use the formula: (percentage / 100) * 360.
Step 5: Plug in the values: (25 / 100) * 360.
Step 6: Calculate the result: 0.25 * 360 = 90 degrees.
Step 7: Conclude that the angle representing Mathematics is 90 degrees.
