Answer:
About [tex]9,693,180\ liters[/tex]
Step-by-step explanation:
we know that
The volume of the tank is equal to the volume of a cylinder plus the volume of hemisphere
so
[tex]V=\pi r^{2}h+\frac{2}{3}\pi r^{3}[/tex]
where
[tex]r=10.5\ m\\h=21\ m\\\pi=3.14[/tex]
substitute
[tex]V=(3.14)(10.5)^{2}(21)+\frac{2}{3}(3.14)(10.5)^{3}[/tex]
[tex]V=7,269.885+2,423.295=9,693.18\ m^3[/tex]
Convert to liters
[tex]1\ m^3=1,000\ L[/tex]
therefore
The volume is equal to
[tex]9,693.18(1,000)=9,693,180\ liters[/tex]
