In a pie chart representing the sales of four products A, B, C, and D, if the angle for product A is 90 degrees, what percentage of total sales does it represent? (2023)
Step 1: Understand that a pie chart is a circle that represents total sales.
Step 2: Know that a full circle has 360 degrees.
Step 3: Identify the angle for product A, which is 90 degrees.
Step 4: To find the percentage of total sales for product A, divide the angle of product A by the total degrees in a circle: 90 degrees / 360 degrees.
Step 5: Calculate the result of the division: 90 / 360 = 0.25.
Step 6: To convert this decimal into a percentage, multiply by 100: 0.25 * 100 = 25%.
Step 7: Conclude that product A represents 25% of total sales.
