Best Answer

Pi is a constant because it is the ratio of the circumference to the diameter of a circle and they are always in the exact same proportion.

Did Leonhard Euler made pi?

NO! Of course he didn't make pi. Pi is a constant that describes the ratio between the circumference and diameter of a circle. So he can not have made pi as it is a constant. Also, he didn't discover pi either, the earliest use of this constant is by the egyptians upon building the great pyramid at Giza in which 2*pi was used as the ratio between the height and perimeter of the pyramid. So basically, no.
