iGCSE Mathematics (0580) - C9.4 Statistical charts and diagrams- Exam Style Questions Paper 3- New Syllabus

(a)
The angle for the museum is $90^\circ$. Calculate its share of the total students:
$\frac{90}{360} \times 300 = 75$ students.
✅ Answer: $\frac{90}{360} \times 300 = 75$

(b)
Calculate the pie chart angles for the remaining choices:
Art gallery angle = $\frac{45}{300} \times 360^\circ = 54^\circ$
Sports stadium angle = $\frac{120}{300} \times 360^\circ = 144^\circ$
Zoo angle = $360^\circ – (90^\circ + 54^\circ + 144^\circ) = 72^\circ$

✅ Answer: Sectors drawn with angles $54^\circ$ and $144^\circ$.
