In a survey of 15 students about their how they get to school, 2 said school bus. If this is shown in a circle graph, how many degrees should the school bus sector take up?
📘 Worked solution
1215 of the students chose school bus.A sector's share of the circle graph matches the fraction of the group it represents.
2(215) · 360° = 48°A full circle graph is 360 deg, so multiply the fraction by 360 deg to find the sector's angle.
