Solution:  Let the base radius of the cylindrical vessel be r and its height be h . 

We have , 

               Circumference of the base = 132cm and Height = 25cm

	herefore             2pi r = 132      and    h=25

Rightarrow             2	imes frac227	imes r=132       and   h=25

Rightarrow             r=frac132	imes72	imes22=21        and    h= 25

	herefore             Volume of the vessel = pi r^2h

                                                  =frac227	imes(21)^2 	imes25 cm^3=34650cm^3

                                                   = frac346501000litres=34.65litres              [ecause 1000cm^3=1 litres]

 Hence , the vessel can hold 34.65 litres of water .
