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)?
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 $$=\dfrac{17.4\times 360}{100}=62.64 ~ 63^\circ$$
