As a child, you may recall learning about Pi in math class. Remembering the term may have triggered a smell of your grandmother’s baked pies. However, that isn’t quite what your math teacher meant during that lesson.
It was first called “pi” in the year 1706 by William Jones, the Welsh mathematician. Pi is the first letter in the Greek word perimitros, which means “perimeter.”
Pi is approximately 3.142 and it is the circumference of any circle that is divided by its diameter. The word Pi comes from the Greek letter π. It is pronounced “pie” and is one of the most common constants in math.
To arrive at pi, you must correctly use the formula. The circumference of a circle is found using the formula C= π*d = 2* π*r. When using a calculator to compute pi, the results should always be approximately 3.14.
Several math lovers have dubbed March 14 or 3/14 as the day to honor the infamous mathematical constant. However, unlike the date, Pi cannot be written like a fraction since it is an infinite number.
Pi is usually used in the subjects of both science and math, but mostly associated with math. When determining the area or circumference of a circle or a round object, students use the Pi formula.
No other math formula is as popular as Pi. It was discovered long ago that Pi turns out as an irrational number and its exact value is not known. However, its formula stands strong in mathematics for centuries.
