Answer:
1583 cubic feet
Explanation:
To find volume of this tank, we need formula for volume of cylinder. Shown below:
Volume of Cylinder =

Where
r is the radius (half of diameter)
h is the height
Given, diameter = 12, hence radius = 6
r = 6
and
Height = 14
h = 14
Now we substitute into formula and use 3.14 for
, to get:

Rounded to nearest whole number, the volume is:
1583 cubic feet
