A student wants to calculate the volume of a metal tube 3.47±0.05m long. She measures the diameter of the tube in a number of places along its length. Her results (in m) are shown below: D = 0.48, 0.47, 0.49, 0.48, 0.50, 0.45 a) The percentage uncertainty in the length (I) b) The mean value of D (in m) c) The range in measurements of D d) The absolute uncertainty in D (in m) e) The percentage uncertainty in D(2 marks) f) The volume of the metal tube using the formula below. State your answer to 2decimal places.(2 marks) V=\frac{\pi D^{2} l}{4} g) The percentage uncertainty in V h) The absolute uncertainty in V
