Patents on the soles of your shoes...: Freebies on Pi Day (3.14)

Each year, on March 14 (3.14), since 1988, the world celebrates Pi Day, in honor of Pi, one of the most well known mathematical constants, representing the ratio of a circle’s circumference to its diameter. An irrational number (3.141592654…..), calculated to its first 62.8 trillion decimal places, in 2021, by the University of Applied Sciences in Switzerland, represented by the Greek letter π (pronounced Pi, like “apple pie”).

Pi is useful on more counts that one. For example (below) it is used calculate the circumference of circles. The circumference of a circle is the distance around a circle. If π = C/d, then C = πd. You can also calculate the circumference of a circle with C = 2πr.
