The volume not included in the vital capacity is the residual volume (RV). Residual volume is the amount of air that remains in the lungs after a maximal exhalation and cannot be voluntarily expelled. Vital capacity, which consists of tidal volume, inspiratory reserve volume, and expiratory reserve volume, measures the maximum amount of air a person can exhale after a deep breath, excluding the residual volume.
Volume of a cylinder = (pi) x (radius of the end)2 x (length)
Density is the amount of mass per unit of volume. Density = mass/volume Mass is the amount of matter in a sample. Length is the longest extent of anything as measured end to end. Volume is the amount of three-dimensional space occupied by a solid, liquid, or gas.
A good place to measure is the diameter of the circular end. That gives you the area of the circular end, and the only other number you need in order to calculate the cylinder's volume is its straight length.
The volume of any cylinder is (pi) x (radius of the circular end)2 x (length of the cylinder)
