The capacity of a

Answer :

Let the radius of the circular end be "r".

The volume of cylindrical vessel = 15.4 litres
1 litre = 1/1000 m3
= 0.0154 m3


 r2h = 0.0154 m3


( ×r ×r × 1) m = 0.0154 m3


r = 0.07 m


TSA of vessel = 2πr (r + h)


= 2 ×  × 0.07 (0.07 + 1)


= 0.44 × 1.07


= 0.4708 m2


Height (h) of cylindrical vessel = 1 m


Therefore, the metal sheet would be required to make the cylindrical vessel is 0.4708 m2
