Question

the curved surface area of a cylinder is 6600 cm square and the sum conference of its base is 220 cm find the capacity of cylinder in litres​

Answer 1

Answer:

C.S.A. Of cylinder =2πrh= 6600 square cm

circumference of cylinder =2πr =220cm

2 πr = 220

r = 220×7/22×2

r=35 cm

2πrh = 6600

h= 6600 ×7/22×35×2

h=30 cm

volume of cylinder = π r^2 h

=3850 cm^3

capacity = 1000 cm^3 = 1 L

1cm^3 =1/1000 L

3850 cm^3 = 1/1000 ×3850 L

=3.850 L Ans.....
