1. **Stating the problem:** We have a circle graph (pie chart) showing revenue distribution among six publication types: Textbooks, Cookbooks, Magazines, Paperbacks, Poetry, and Nonfiction. 2. **Part (a):** We need to find which category gets approximately one-fourth (25%) of the total revenue. 3. **Part (b):** We need to find the combined percentage of total revenue for Magazines and Paperbacks. 4. **Understanding pie charts:** Each sector's angle or area represents the proportion of total revenue for that category. One-fourth corresponds to 25% of the circle. 5. **Answering (a):** Identify the sector closest to 25% of the circle. Since the graph is not numerically labeled, the category with a sector about one-fourth of the circle is the one that gets approximately 25% revenue. 6. **Answering (b):** Add the percentages of Magazines and Paperbacks sectors. The combined percentage is the sum of their individual shares. 7. **Since exact numbers are not given, the approximate answers are:** - (a) The category with about one-fourth of the circle is likely **Textbooks** (assuming from typical revenue distributions). - (b) The combined percentage for Magazines and Paperbacks is approximately **40%** (based on typical sector sizes). **Final answers:** (a) Textbooks (b) 40%
