Question

Draw a pie chart of the areas of continents of the world given in the following table:

Continents	Asia	Antarctica	Africa	Europe	South America	North America	Australia
Area in million sq. km	$43.8$	$13.7$	$30.3$	$10.1$	$17.8$	$24.4$	$9.0$

Accepted Answer

Given,

The areas of continents of the world given in the following table:

Continents Asia Antarctica Africa Europe South America North America Australia

Area in million sq. km $43.8$ $13.7$ $30.3$ $10.1$ $17.8$ $24.4$ $9.0$

The following procedure to use to construction of a pie chart:

Draw a circle of a suitable radius.

Find the aggregate of all the components.

Use the following formula to get the angles corresponding to the different components: $Angle = \frac{Value of each component}{Aggregate of all components} \times 360 °$

Draw the angles calculated in step $3$ at the centre of the circle.

Computation of central angles.:

Continents Area in million sq. km Measure of central angles

Asia $43.8$ $\frac{43.8}{149.1} \times 360 ° = 105.75 °$

Antarctica $13.7$ $\frac{13.7}{149.1} \times 360 ° = 33.07 °$

Africa $30.3$ $\frac{30.3}{149.1} \times 360 ° = 73.15 °$

Europe $10.1$ $\frac{10.1}{149.1} \times 360 ° = 24.38 °$

South America $17.8$ $\frac{17.8}{149.1} \times 360 ° = 42.97 °$

North America $24.4$ $\frac{24.4}{149.1} \times 360 ° = 58.95 °$

Australia $9.0$ $\frac{9}{149.1} \times 360 ° = 21.73 °$

Total $149.1$ $360 °$

Hence, the required answer is shown above.

Draw a pie chart of the areas of continents of the world given in the following table:

Continents Asia Antarctica Africa Europe South America North America Australia

Area in million sq. km $43.8$ $13.7$ $30.3$ $10.1$ $17.8$ $24.4$ $9.0$
