Question

Marks obtained in four subjects are represented in a pie chart. Match marks obtained with its central angle.

• A. 140${}^{\circ }$
• B. 70${}^{\circ }$
• C. 90${}^{\circ }$
• D. 60${}^{\circ }$

Answer 1

Total marks = 70 + 35 + 45 + 30 = 180

Angle of the sector representing marks in Math $=\frac{70}{180}\times {360}^{\circ }={140}^{\circ }$

Angle of the sector representing marks in Eng $=\frac{35}{180}\times {360}^{\circ }={70}^{\circ }$

Angle of the sector representing marks in Bio $=\frac{45}{180}\times {360}^{\circ }={90}^{\circ }$

Angle of the sector representing marks in Phy $=\frac{30}{180}\times {360}^{\circ }={60}^{\circ }$
