How does one solve this problem?

Answer 1

5.99 feet.

Explanation:

If the radius of the base of a right cylinder is r and its length is l, then the volume of the cylinder will be
`V = \pi r^(2) l`

Now, it is given that the volume(V) of the cylindrical tank is 2279.64 cubic feet and radius(r) of its base is 11 feet.

Therefore, the equation for getting the length(l) is

`2279.64 = \pi (11^(2) ) * l`

⇒
`l=(2279.64 * 7)/(22 * 121) = 5.99` feet.

So, the length of the tank is 5.99 feet. (Answer)
