a. Calculate the following: (a) volumes (in cubic meters) of the tank in each trial (Hint: formula for volume cylinder = Tr²h, where r = radius, h = height), (b) mean of the volume, (c) standard deviation of the volume, and (d) CV of the volume b. Report the average volume of this cylindrical tank together with its uncertainty considering that its average radius is 2.70 ± 0.01 m.
