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.
    Some other possibilities for your question:     1. area/circumference = r/2     2. circumference/area = 2/r     3. Ratios are fractions, and pi is a ratio between the circumference of a circle and its diameter.ractions consist of two numbers: a numerator (which is above the line) and a denominator (which is below the line). So to work out the square root of a fraction you find the square root of the numerator and put it above the square root of the denominator.
