Question

The radius of a cylindrical water tank is 5.5ft, and its height is 13ft. What is the volume of the tank? Use the value3.14 for pie , and round your answer to the nearest whole number. Be sure to include the correct unit in your answer.

Answer 1

`1235 ft^3`

Explanation:

The tank is cylindrical and the volume of a cylinder is given as:

`V = \pi r^2h`

where r = radius of the cylinder = 5.5 ft

h = height of the cylinder = 13 ft

Using the value of 3.14 for π, the volume of the tank is:

`V = 3.14 * 5.5^2 * 13\\\\V = 1234.805ft^3`

Rounding off to the nearest whole number, the volume of the tank is
`1235 ft^3`
