Question

The following table shows the monthly budget of a family. Draw a pie chart using the angle measurement.

Particulars	Food	House Rent	Clothing	Education	Savings	Miscellaneous
Expenses(in Rs.)	$4800$	$2400$	$1600$	$800$	$1000$	$1400$

Answer 1

The central angle for various components may be calculated as follows.

Particulars	Expenses(Rs.)	Central angle
Food	$4800$	$\frac{4800}{12000}\times {360}^o={144}^o$
House rent	$2400$	$\frac{2400}{12000}\times {360}^o={72}^o$
Clothing	$1600$	$\frac{1600}{12000}\times {360}^o={48}^o$
Education	$800$	$\frac{800}{12000}\times {360}^o={24}^o$
Savings	$1000$	$\frac{1000}{12000}\times {360}^o={30}^o$
Miscellaneous	$1400$	$\frac{1400}{12000}\times {360}^o={42}^o$
Total	$12000$	${360}^o$

Clearly, we obtain the required pie chart as shown.
