Final answer:
The square root of pi (π) is an irrational number, which if approximated, is approximately 1.77245385091. The correct answer to the question is D.
Step-by-step explanation:
If we are to address the question "What's the square root of pie?", firstly, it should be clarified that the mathematical constant pi (π) is the ratio of a circle's circumference to its diameter, typically approximated as 3.14.
However, the actual value of π is an irrational number that extends to infinity, and cannot be expressed exactly as a finite decimal.
Now, the square root of π (√π) is also an irrational number.
If we were to provide an approximate value, which is commonly done in mathematics to make certain calculations more manageable, the square root of π would be approximately 1.77245385091.
To obtain this figure, most would use a calculator or mathematical software, as calculating square roots of irrational numbers by hand is not practically feasible.
Therefore, the correct answer to the question would be D.
The square root of pie is 1.77245385091 (approximate value).
It is important to note that in mathematics, the use of approximate values is often adequate for practical purposes, as long as we are aware of the limitations of such approximations.
