the volume of a cylinder is Pi*radius squared * length (or height). If
you do the measurements in centimeters the answer is in cubic
centimeters, and one cubic centimeter is equal to a milliliter. 1000
milliliters equals one liter. Hence measure the barrel, determine the
volume in liters. then the ratio of the height of the 110 liter mark,
divided by the height barrel will be equal to the ratio of 110L/ volume
of the barrel. Twice that high will be the 220 L mark. This assumes
that the barrel is a true cylinder. If not all bets are off.

yep that will work too.
