Question

Monthly expenditure of a family be as follows:show that data on a pie chart.

Answer 1

Sum of all components$=3200+2400+1200+1200+800+800=9,600‬$

We know that Central angle$=\frac{valueofcomponent}{Sumofallcomponents}\times {360}^{\circ }$

Item	Amount	Central angle
Rent	$3200$	$\frac{3200}{9,600‬}\times {360}^{\circ }={120}^{\circ }$
Food	$2400$	$\frac{2400}{9,600‬}\times {360}^{\circ }={90}^{\circ }$
Clothing	$1200$	$\frac{1200}{9,600‬}\times {360}^{\circ }={45}^{\circ }$
Education	$1200$	$\frac{1200}{9,600‬}\times {360}^{\circ }={45}^{\circ }$
Entertainment	$800$	$\frac{800}{9,600‬}\times {360}^{\circ }={30}^{\circ }$
Savings	$800$	$\frac{800}{9,600‬}\times {360}^{\circ }={30}^{\circ }$
