Pi Day

Pi (𝛑) is one of the most common and popular mathematical constants as 𝛑 plays a central role in Geometry, more specifically in circles. One may recall that the perimeter and area of a circle is 2𝛑r/𝛑d and 𝛑r2 respectively. 𝛑 is also an irrational number and thus cannot be expressed as the ratio between two whole numbers.
