In a pie chart, the central angle of each slice of the pie is proportional to its value as compared to the total value.
θ = \(\rm \frac{\text{Value of Slice.}}{\text{Total Value.}}\times360^\circ\)
Calculation:
Angle corresponding to the Science graduates = θ = \(\rm \frac{\text{Number of Science graduates.}}{\text{Total number of graduates.}}\times360^\circ\).
= \(\rm \frac{30}{30+70+50}\times360^\circ\)
= \(\rm \frac{30}{150}\times360^\circ\)
= 72°.
