Question

The Curved surface area of a cylinder is 6600 square Cm and the circumference of its base is 220 Cm. Find the capacity of the cylinder.

Answer 1

C.S.A. Of cylinder =2×pie×r×h= 6600 square cm
circumference of cylinder =2×pie×r =220cm
2 ×pie ×r =220
r = 220×7/22×2
r=35 cm
2×pie×r×h =6600
h= 6600 ×7/22×35×2
h=30 cm
volume of cylinder =pie×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

Answer 2

Answer:

Step-by-step explanation:



Given,

Curved surface area of cylinder = 6600 cm²

Circumference of its base = 220 cm

First we find radius,

so, circumference of a cylinder = 220 cm

2πr = 220 cm

2×22/7×r = 220 cm

r = 220×7/2×22

r = 5×7

r = 35 cm

Than,

C.S.A of cylinder = 6600 cm²

2πrh = 6600 cm²

2×22/7×35×h = 6600 cm²

h = 6600×7/2×22×35

h = 30 cm

Capacity of a cylinder = volume of a cylinder

= πr²h

= 22/7×35×35×30

= 22×5×35×30

= 110×35×30

= 3850×30

= 115500 cm

Change into litre

= 115500/1000

= 115.5 litre
