Respuesta :

Given: The radius of a cylindrical water tank is 6.5 ft, and its height is 9 ft.

Required: To determine the volume of the tank.

Explanation: The volume of a cylinder of height h and radius r is-

[tex]V=\pi r^2h[/tex]

Here we have,

[tex]\begin{gathered} r=6.5\text{ ft} \\ h=9\text{ ft} \end{gathered}[/tex]

Hence, the volume of the tank is-

[tex]V=3.14\times(6.5)^2\times9[/tex]

Further simplifying as-

[tex]\begin{gathered} V=1193.985\text{ ft}^3 \\ V\approx1194\text{ ft}^3 \end{gathered}[/tex]

Final Answer: The volume of the tank is 1194 cubic ft.
