Question

A pie chart represents the scores obtained in four subjects. Match each score with its central angle.

Answer 1

Total score = 80 + 60 + 70 + 30 = 240

Angle of the sector representing the score in mathematics $=\frac{80}{240}\times {360}^{\circ }={120}^{\circ }$

Angle of the sector representing the score in science
$=\frac{60}{240}\times {360}^{\circ }={90}^{\circ }$

Angle of the sector representing the score in drawing $=\frac{70}{240}\times {360}^{\circ }={105}^{\circ }$

Angle of the sector representing the score in communication $=\frac{30}{240}\times {360}^{\circ }={45}^{\circ }$

Let's represent the above information in a pie chart.
