The volume of a cylindrical capillary tube is given by V = ? r^2h where r is its radius and h its height. If the radius of the capillary tube is found to be 0.030 ± 0.002 cm and the height found to be 4.0 ± 0.1 cm, what is the volume of the capillary tube and its associated error? What measurement must be made to a higher precision to decrease the error in the volume?
