The volume of a right cylinder can be calculated using the formula:

V = πr^2h

where V is the volume, r is the radius of the base, and h is the height.

The diameter of the cylinder is 12 meters, so the radius is half of that, or 6 meters. The height of the cylinder is 16 meters.

Putting these values into the formula, we get:

V = π(6 meters)^2(16 meters)

V = 1,814.37 cubic meters (rounded to two decimal places)

Therefore, the volume of the tank is 1,814.37 cubic meters
