The formula for the volume of the cylinder is:
[tex]V=\pi\cdot r^2\cdot h[/tex]
In this case, r=5ft, h=9ft and pi=3.14, then:
[tex]\begin{gathered} V=\pi\cdot r^2\cdot h \\ \Rightarrow V=(3.14)\cdot(5^2)\cdot9=3.14\cdot225\cdot9 \\ =3.14\cdot225=706.5 \\ V=706.5 \end{gathered}[/tex]
Therefore, the volume of the cylinder is 706.5 ft^3
