The whole circle is 100%, which equals  \n360◦ . To 􀀂nd the amount for a slice, multiply its percent (as a decimal) by the total. To 􀀂nd a slice’s central angle, multiply its percent by 360◦ . All the slices add up to 100% .  \n▷ Example: In a survey of 200 people, 25% chose pizza. How many people chose pizza? Work: Change 25% to 0.25 and multiply by the  \ntotal: 0.25 􀀂 200. ⋆ Answer: 50 people  \nWhole circle = 100% = 360◦ .  \n♦ Practice Problems  \nUse each circle graph.

For the 􀀂rst chart, the total is given right in the title: “Lunch choices: 240 students.” The whole circle represents all 240 students, so no calculation is needed for this one.  \n2. Pizza is 25% of the lunch chart. Change 25% to 0.25 and multiply by the total number of students: 0.25 􀀂 240 = 60, so 60 students chose pizza.  \n3. Tacos are 20% of the 240 students. Since 20% = 0 .20, multiply  \n0.20 􀀂 240 = 48, so 48 students chose tacos.  \n4. Salads are 15% of the group. Use the same percent-of-a-total idea:  \n0.15 􀀂 240 = 36, so 36 students chose salads.  \n5. Sandwiches are the largest slice at 30% . Multiply 0.30 by the total, 0.30 􀀂 240 = 72, so 72 students chose sandwiches.  \n6. The Other slice is 10% of the students. Because 10% means one tenth, 0.10 􀀂 240 = 24, so 24 students chose other lunches.  \n7.
