On simplifying we get ph r 1 - r 2. The Formula for Volume of Hollow Cylinder. The volume of a cylinder formula is given by.
The volume of a tube can be used to determine how much material is needed to construct shapes such as a hose or a pipe.
A tube is a hollow cylinder like the one shown below. Suppose r 1 and r 2 are the two radii of the given hollow cylinder with h as the height then the volume of this cylinder can be written as. A hollow cylinder is one type of cylinder which is hollowIt has two radiusR is exradiusr is Inside circle radius. V phr 1 2 r 2 2.
