How do you calculate fluid volume in a cylindrical container?

Answer 1

Capacity of the container = (pi) x (radius of the round end)2 x (height of the cylinder).

That's the capacity of the container. If the volume of the fluid in it is really what you want,

then you can use the same formula, but instead of the full height of the container, use only

the height of the fluid column, i.e. what we professionals would technically refer to as the "depth".
