PIR^2

Pi R^2 is the formula used to calculate the area of a circle I wanted to try and generate a font that only used the most basic of geometrical shapes the Circle and the Square however I had to add the humble Triangle to this list in order to create Pi R^2 my latest font and first commercial font.

The number Pi is a mathematical constant that is the ratio of a circle’s circumference to its diameter. The constant, sometimes written pi, is approximately equal to 3.14159.
It has been represented by the Greek letter “π” since the mid-18th century. Pi is an irrational number, which means that it cannot be expressed exactly as a ratio of two integers (such as 22/7 or other fractions that are commonly used to approximate Pi); its decimal representation never ends and never repeats.
Pi Day and Pi Approximation Day are two unofficial holidays held to celebrate the mathematical constant Pi. Pi Day is celebrated on March 14, or in the month/day date format as 3/14; since 3, 1 and 4 are the three most significant digits of pi. March 14 is also the birthday of Albert Einstein so the two events are sometimes celebrated together. Pi Approximation Day is held on July 22, or in the more common day/month date format as 22/7, which is an approximate value of Pi.
