Question

$\text{The following date shows the agricultural production in India during a certain year.}$

$\begin{array}{ccccc}\text{Foodgrain}& \text{Rice}& \text{Wheat}& \text{coarse cereals}& \text{Pulses}\\ \text{Production}& 57& 76& 38& 19\\ \text{(in millions of tonnes)}& & & & \end{array}$

$\text{Draw a pie chart to represent the above data.}$

Answer 1

$\text{Total number of million of tonnes of foodgrains = 57 + 76 + 38 + 19 = 190 million of tonnes}$

$\begin{array}{ccc}\text{Foodgrain}& \text{Production (in million of tonnes)}& \text{Central angle}\\ \text{Rice}& 57& \frac{57}{190}\times {360}^{\circ }={108}^{\circ }\\ \text{Wheat}& 76& \frac{76}{190}\times {360}^{\circ }={144}^{\circ }\\ \text{Coarse cereals}& 38& \frac{38}{190}\times {360}^{\circ }={72}^{\circ }\\ \text{Pulses}& 19& \frac{19}{190}\times {360}^{\circ }={36}^{\circ }\\ \text{Total}& 190& {360}^{\circ }\end{array}$

$\text{(i) Draw a circle with suitable radius.}\text{(ii) Draw a horizontal radius.}\text{(iii) Starting with this radius, draw sectors of central angles}{108}^{\circ },{144}^{\circ },{72}^{\circ }and{36}^{\circ }\text{respectively}\text{(iv) Shade these sectors with different colours or designs as shown in the figure.}$
