Answer:
The approximate volume of the tank is [tex]V=16,747\ ft^{3}[/tex]
Step-by-step explanation:
we know that
The volume of a hemisphere (water storage tank) is equal to
[tex]V=\frac{4}{6}\pi r^{3}[/tex]
we have
[tex]r=20\ ft[/tex]
assume
[tex]\pi =3.14[/tex]
substitute
[tex]V=\frac{4}{6}(3.14)(20)^{3}[/tex]
[tex]V=16,747\ ft^{3}[/tex]
