Question

The radius of a cylindrical water tank is 6.5 ft, and it’s height is 9 ft. What is the volume of the tank? Use the value 3.14 for n, and round your answer to the nearest whole number. Be sure to include the correct unit in your answer.

Answer 1

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-

`V=\pi r^2h`

Here we have,

`\begin{gathered} r=6.5\text{ ft} \\ h=9\text{ ft} \end{gathered}`

Hence, the volume of the tank is-

`V=3.14*(6.5)^2*9`

Further simplifying as-

`\begin{gathered} V=1193.985\text{ ft}^3 \\ V\approx1194\text{ ft}^3 \end{gathered}`

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