Questions & Step-by-Step Solutions
If a pie chart indicates that 10% of a population prefers classical music, what is the angle in degrees that represents this preference?
Step 1: Understand that a pie chart represents a whole circle, which is 360 degrees.
Step 2: Know that the percentage given (10%) needs to be converted into a fraction for calculation.
Step 3: Convert 10% into a decimal by dividing by 100, which gives you 0.10.
Step 4: Multiply the decimal (0.10) by 360 degrees to find the angle that represents the preference.
Step 5: Calculate 0.10 * 360, which equals 36 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.
