3.14* diameter*Depth * 7.48 = gallons (diameter and depth in feet)


3,14*diameter gives you the circumference of the circle. When multiplied
by
the depth, it gives you the surface area of the right circular cylinder,
not its volume.



Correct. My mistake.

3.14 * (1/2 diameter) * (1/2 diameter )*depth * 7.48 = gallons.

Sorry
