Answer:Total 100% or 25 studentsSwimming 36%  or 9 studentsLacrosse 48%  or 12 students Volleyball 16% or 4 studentsStep-by-step explanation:To do a circle graph, you draw a circle and divide it into all sections.To know the size of each section, you need to know the total number of every category.You could draw it with percent.100% is total, and you know the percent of each sport.They told you 12 students choose lacrosse so, this represents 48%.Now, you can find the other numbers with cross-multiplication.48%____12100%____X=X=(100x12)/48=25Total students: 25Students that named lacrosse: 12 or 48%100%____2516%____X=X=(16x25)/100=4Students that named Volleyball: 4 or 16%100%____2536%____X=X=(36x25)/100=9Students that named Swimming: 9 or 36%To confirm: 12 + 9 + 4 = 25
