答案 B
解析 The correct answer is B. To solve this problem, find the angle measure of a sector of a circle that encompasses 20% of the circle. Because there are 360° in a whole circle, a sector that is 20% of the circle would have an angle measure of 20% of 360°, or(0.20)(360°), which is 72°. Thus Quantity B(75°)is greater than Quantity A(72°).
