If 2014 figures for Cement are plotted on a pie-chart, approximately what angle will be sub-divided by 'Expenditure'? (in degrees)

Solution

From the table,

Expenditure for Cement in 2014 = 2628

$$\therefore\ $$Angle sub-divided by Expenditure in the pie-chart = $$\frac{2628}{3018+2628+312+204+16}\times360^{\circ}$$

$$=\frac{2628}{6178}\times360^{\circ}$$

$$=153^{\circ\ }$$

$$=150^{\circ\ }$$ (approximately)
