Question

find the C.S.A of the figure ​

Answer 1

c.s.a of a figure = 2πrh

= 2* 22/7* 6* 3

= 132/7 *6

= (792/7) m

Now you can keep it like this

or

divide it will come In point

it's better to keep like this

Answer 2

Answer:

csa of the following figure=csa of cylinder+csa of cone

Step-by-step explanation:

csa of cylinder= πr^2h

= 22/7 x 6 x 6 x 10

= 1131.42

csa of cone = πrl

= 22/7 x 6 x l

= 18.85l

l^2=h^2+r^2

l2 = 9 + 36

l2 = 45

l = √45

l = 6.7

therefore total csa of cone = 18.85 x 6.7

= 126.3(approx)

there total csa of the figure :-

1131.42+126.3=1257.72
