Which one of the following bar graphs could represent the data from the circle graph shown?
Answer: C
Small hint:
Decide what fraction of the whole circle each of the three regions takes up
Big hint:
Each shaded region is a quarter and the unshaded region is a half, so the three bars should have heights in the ratio
Solution:
The two shaded regions are each one quarter of the circle, and the unshaded region is one half. So the three quantities are in the ratio or
A matching bar graph must have the two shaded bars equal in height and the unshaded bar exactly twice as tall. Only one bar graph has two equal shaded bars with the white bar double their height.
Thus, the correct answer is C .
