In lab, you will be filling a 12-mm-diameter test tube with fluid. Assuming that the test tube is a perfect cylinder (volume = r^2h, where r is the radius and h is the height), what is the height (in cm) of 2.0 mL of fluid? [Record this value in your lab notebook, since you will need it for Experiment 1.] Recall that 1 mL = 1 cm^3
