11000 litre of water is needed to fill the tank.

Answer:

solution given:

radius [r]=1.05m

Total height[H]=3.5m

height of cylinder[h]=2.45m

Now

The volume of the cylindrical part of tank=
$\pi r^2h=3.14*1.05^2 *2.45=8.4815m^3$

again

the volume of semi-spherical part of tank=
$(2)/(3) \pi r^(3) =(2)/(3)*3.14*1.05^3=2.4233m^3$

now

total volume=volume of the cylindrical part of tank + volume of semi-spherical part of tank

=8.4815+2.4233=10.9048
m^(3)

we have

1m^3=1000litre

$10.9048m^3=1000*10.9048=10904.8\:litre$
