The capacity of a closed cylindrical vessel of height 1 m is 15.4 liters. How many square meters of metal sheet would be needed to make it? (pi=22/7)
Height of the vessel = 1 m
Capacity of the vessel = 15.4 litres
Volume of the cylindrical vessel =
Metal sheet needed to make the cylindrical vessel.
= Total surface area of the cylindrical vessel.
= 2
r(r + h)
= 0.4708 m2
Therefore, 0.4708 m2 of sheet will be required to make the vessel.
