Answer:

$8\:\mathrm{minutes}$

Step-by-step explanation:

The volume of a cylinder is given as:

$r^2\cdot\pi\cdot h$

Since the diameter is $2.2$ , the radius is $\frac{2.2}{2}=1.1$ .

Therefore, the volume of this cylinder is:

$1.1^2\cdot 3.14\cdot 4=15.1976\:\mathrm{ft^3}$ , using $\pi=3.14$ as requested in the problem.

Since the tank is emptied at a constant rate of $1.5\:\mathrm{ft^3\:per\:minute}$ , it will take

$\frac{15.1976}{1.5}=7.5988=\fbox{$8\:\mathrm{minutes}$}$ to empty the tank.
