To determine which pair of values makes the volume an irrational number, we need to consider the value of π (pi) in the formula.
The formula for the volume of a cylinder is given by: V = πr^2h
Since the engineer is using an approximation of 22/7 for π, the volume will only be an irrational number if the values of r and h result in an irrational value for V when multiplied by π.
Therefore, we can conclude that the pair of values that makes the volume an irrational number is not provided in the given information. More information is needed about the values of r and h.
