Question

Answer in detail:
Draw a pie-diagram using the following data:

Subject	% of Marks
Economics	30
English	20
Marathi	10
O.C.	15
S.P	10
B.K.	15

Answer 1

The central angle $=\frac{componentvalue}{sumofallcomponents}\times {360}^{\circ }$

Total amount$=30+20+10+15+10+15=100$

Hence, the central angle for each activity will be calculated as follows

Subject	$\%$ of marks	Central angle
Economics	$30$	$\frac{30}{100}\times {360}^{\circ }={108}^{\circ }$
English	$20$	$\frac{20}{100}\times {360}^{\circ }={72}^{\circ }$
Marathi	$10$	$\frac{10}{100}\times {360}^{\circ }={36}^{\circ }$
O.C	$15$	$\frac{15}{100}\times {360}^{\circ }={54}^{\circ }$
S.P	$10$	$\frac{10}{100}\times {360}^{\circ }={36}^{\circ }$
B.K	$15$	$\frac{15}{100}\times {360}^{\circ }={54}^{\circ }$
