OBJECTS HIT

If the data of the bar diagram is represented by a pie-chart, and the angle of a sector of the pie-chart is 36°, then this sector represents the accidents involving.

A. Pedestrians

B. Bicycles

C. Buses

D. Stationary vehicles

Solution:

\begin{aligned} ∴ 360^{\circ} = 1000 Accidents \\ 1^{\circ} = \frac{1000}{360^{\circ}} \\ 36^{\circ} = \frac{1000}{360^{\circ}} \times 36^{\circ} \\ = 100 Accidents \end{aligned}

It is the accidents of Stationary vehicles
