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 itslength. 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 (1) b) The mean value of D (in m) The range in measurements of D ) The absolute uncertainty in D (in m) The percentage uncertainty in D O The volume of the metal tube using the formula below. State your answer to 2 decimal places. ) The percentage uncertainty in V -) The absolute uncertainty in V
