Question 65

Table shows the production of rice (in million tonnes) of three states over six years.

If the total production in three states in all six years is represented by a pie-chart, what is the central angle of the sector representing production in the year 2014, (to nearest whole number)?

Solution

From the above table,

Total production of the rice in the year of 2014 $$=6.2+4.8+6.4=17.4$$million tonnes

Total production of the rice in all the six years $$=100$$ million tonnes

Hence the angle subtended at the center $$=\dfrac{17.4\times 360}{100}=62.64 ~ 63^\circ$$
