Is the first 3 a digit of pi?

It's 3. Obviously. Without changing the meaning of "first", "digit", "pi", or altering our representation of the number, it's entirely unambiguous. Pi consists of digits, and the first of those is the digit 3.

What is the full number of pi?

Regardless of the circle's size, this ratio will always equal pi. In decimal form, the value of pi is approximately 3.14. But pi is an irrational number, meaning that its decimal form neither ends (like 1/4 = 0.25) nor becomes repetitive (like 1/6 = 0.166666...). (To only 18 decimal places, pi is 3.141592653589793238.)

Who memorized 42195 digits of pi?

Hiroyuki Gotō (後藤 裕之, Gotō Hiroyuki, born in Tokyo, Japan) recited pi from memory to 42,195 decimal places at NHK Broadcasting Centre, Tokyo on 18 February 1995. This set the world record at the time, which was held for more than a decade until Lu Chao beat it in 2005.

Is pi an infinite?

Pi is a number that relates a circle's circumference to its diameter. Pi is an irrational number, which means that it is a real number that cannot be expressed by a simple fraction. That's because pi is what mathematicians call an "infinite decimal" — after the decimal point, the digits go on forever and ever.

Who invented zero?

About 773 AD the mathematician Mohammed ibn-Musa al-Khowarizmi was the first to work on equations that were equal to zero (now known as algebra), though he called it 'sifr'. By the ninth century the zero was part of the Arabic numeral system in a similar shape to the present day oval we now use.
