Q:
# What is the square root of pi?

The square root of pi, like pi itself, is an irrational number. It can be approximated to four decimal places by 1.7725. The factorial of 1/2 is equal to half of the square root of pi.

Continue ReadingThe concept of the mathematical constant pi dates back approximately 4,000 years to ancient Mesopotamia.
