does it make sense if i define that the shape of a circle is infinity, which i write its equation as:(adsbygoogle = window.adsbygoogle || []).push({});

x^2+y^2 = ∞

i know that infinity means very very big until we cannot define how big is it. in this case, is the equation above still valid? can i still say that the shape of this infinity in the equation is a circle? or its size is not important or does not make sense already because infinity doesn't have shape since it's too big until we can't define what's the shape of that "thing"?
