Number of self-Help books sold = 252 books
Step-by-step explanation:
Total books sold last week = 1,125
Central angle for the Self-Help slice = 80.64°
Total angle in a circle = 360°
How many of the books sold were Self-Help books?
Number of self-Help books sold =
Central angle for the Self-Help slice / Total angle in a circle × total number of books sold
= 80.64° / 360° × 1,125
= 0.224 × 1,125
= 252
Number of self-Help books sold = 252 books
