Because if you approximate pi, you get pi = 3.1415926535897932384626433832795...    Square root of 3.1415926535897932384626433832795... is 1.772453850905516027298167483â¦3411...... which is the square root of pi.    Hope that helps.
For example, 4 and â4 are square roots of 16 because 42 = (â4)2 = 16. Every non-negative real number a has a unique non-negative square root, called the principal square root, which is denoted by âa, where â is called the radical sign or radix. For example, the principal square root of 9 is 3, denoted â9 = 3, because 32 = 3 Ã 3 = 9 and 3 is non-negative. The term whose root is being considered is known as the radicand. The radicand is the number or expression underneath the radical sign, in this example 9. Every positive number a has two square roots: âa, which is positive, and ââa, which is negative.
