Question 110

The following data represents the approximate percentage of water in varioous oceans. Prepare a pie chart of the given data.
$\begin{array}{cc}\text{Ocean}& \text{Percentage of water}\\ \text{Pacific}& 40\%\\ \text{Atlantic}& 30\%\\ \text{Indian}& 20\%\\ \text{Others}& 10\%\end{array}$

Answer 1

$\begin{array}{cc}\text{Ocean}& \text{Central angle}\\ \text{Pacific}& \frac{40}{100}\times {360}^{\circ }={144}^{\circ }\\ \text{Atlantic}& \frac{30}{100}\times {360}^{\circ }={108}^{\circ }\\ \text{Indian}& \frac{20}{100}\times {360}^{\circ }={72}^{\circ }\\ \text{Others}& \frac{10}{100}\times {360}^{\circ }={36}^{\circ }\end{array}$
The pie chart is as follows :
