Final answer:
The correct answer is option d) 7 and 8. The value of 9 π/4 falls between the whole numbers 7 and 8, after evaluating the approximate value of π and carrying out the arithmetic operation.
Step-by-step explanation:
The question is asking between which two whole numbers the value of 9 π/4 lies. To find this, we should first approximate the value of π to 3.14. Multiplying 3.14 by 9 gives us 28.26, and then dividing by 4 yields approximately 7.065. Therefore, we can conclude that 9 π/4 is between the whole numbers 7 and 8.
Therefore, the correct answer would be option d) 7 and 8.
