Since we want to calculate the weight of a cylinder, the formula is W = V*D. Or, Weight = Volume*Density. [πr²h is the formula for volume. Pi [3.14159...] x radius squared x height. Simply substitute if you have all aspects of the formula.]
To calculate the weight of a cylinder, you can use the formula: weight = volume x density x acceleration due to gravity. First, calculate the volume of the cylinder using the formula for the volume of a cylinder (pi x radius^2 x height). Then, multiply the volume by the density of the material the cylinder is made of, and finally, multiply the result by the acceleration due to gravity (typically 9.81 m/s^2) to find the weight in Newtons.
The pressure inside an inverted hollow cylinder in water is equal to the pressure at the depth of the cylinder's centroid multiplied by the specific weight of water. To calculate it, use the formula: pressure = (specific weight of water) * (depth of centroid of cylinder).
Formula for a cylinder is pi*radius2*height.
For a right cylinder, the formula for volume is quite simple. It is pi times the radius of the cylinder squared times the height of the cylinder.
What ever was in the cylinder had weight of its' own. When the cylinder was emptied, only the weight of the cylinder was left.
The cylinder will support, at neutral buoyancy, as much weight as the weight of water it could contain, less the weight of the cylinder itself.
The formula for volume of a cylinder is pi•r2•h
You can find the diameter of a cylinder by using the formula for pressure at the base of a cylinder (P = F/A) and the formula for the area of a circle (A = πr^2) where r is the radius of the base. Once you calculate the force acting on the base of the cylinder, you can find the diameter using the formula D = 2r, where D is the diameter.

Because the bases of the cylinder are circles.
