Most scientists say pi is a never ending number. Does this mean it is impossible for a perfect circle to be created?

First, what's this about "most scientists" say pi is never ending? Are there some that don't "believe" this?
Second, what does pi being never ending have to do with drawing a circle? Doesn't a compass work fine?

What your referring to is the fact that pi is an irrational number. This means it is a non-repeating, non-terminating decimal. Pi is nothing more than the ratio of the circumference of the circle to its diameter. So we can easily draw a perfect circle with a compass. This is one of the foundations of geometry that given a center point a radius, we can construct a circle with a compass.
Another example of an irrational number is square root of two, which is also a non-repeating, non-terminating decimal. We can certainly draw a square with sides 1. When we do this we have that the diagonal of this square has length sqrt(2).

Yes. It is impossible to draw a perfect circle, since we cannot get the points exactly correct. However, we can draw a circle close enough to perfect to treat it like one.

You can create a perfect circle using a compass. You just can't calculate the exact ratio between the radius and the circumference.

Mathematicians create perfect circles all the time. But it's done abstractly.

no, get one of those jobbies with one pointed end, and the other end holds a pencil. That is a perfect circle.

i think you have right since the length of the sircle is 2*pi*r.

Hello
nothing is ever perfect
pi proves this theory
Hope this helps
good luck with the answers

Well you can draw one with out raising your hand- doing it in 2 motions so...I guess your body agrees with mathematics...hmmm
