Ferdinand von Lindemann proved, in 1882, that pi was transcendental.
Nobody is responsible. Different groups have decided, on their own, to calculate pi to many digits - as a sort of challenge.
Finding the area of a circle: pi*radius2 Finding the circumference of a circle: 2*pi*radius or diameter*pi Finding the surface area of a sphere: 4*pi*radius2
there are infinite numbers in pi
They both use pi:- circumference = 2*pi*radius or diameter*pi area = pi*radius2
The circumference of a circle divided by its diameter is the value of pi and pi has a wide range of uses some of which are:- Finding the volume of a sphere Finding the surface area of a sphere Finding the volume of a cone Finding the volume of a cylinder Finding the area of a circle Finding the circumference of a circle
Pi belongs to the sets of real numbers, transcendental numbers and irrational numbers.
The first numbers of pi is 3.14159265358979323846264338327950288419716939937510 58209749445923078164062862089986280348253421170679
Pi= 3.14159265
Pi is very important for finding circumfrences and area's of circles.
pi is infinite pi is about 3.1415
The first twelve numbers of pi are 3.14159265358
He did some of the numbers in Pi.
