Question

the circle graph shows how much revenue a publisher gets for different types of publications. use this graph to answer the questions below.
(a) which category gets approximately one - fourth of the total revenue?
(b) approximately what share of the total revenue goes to cookbooks and paperbacks combined?
poetry
nonfiction
magazines
o 20%
o 60%
o 60%

Explanation:

Step1: Analyze sector size

In a circle graph (pie - chart), one - fourth of the total is equivalent to \(25\%\) (since \(\frac{1}{4}=0.25 = 25\%\)). By visually comparing the sectors, the "Textbooks" sector appears to be approximately one - fourth of the circle.

Step2: Calculate combined percentage

For part (b), assume the total percentage is \(100\%\). Let's estimate the percentages of "Cookbooks" and "Paperbacks". If we assume the "Cookbooks" sector is about \(15\%\) and the "Paperbacks" sector is about \(5\%\) (by visual inspection of the pie - chart sectors relative to the whole circle), then the combined percentage is \(15\%+5\% = 20\%\).

Answer:

(a) Textbooks; (b) \(20\%\)
