the value of r= x^2+y^2+z^2

First,

[tex]r=||\textbf{r}||=\sqrt{x^2+y^2+z^2}\neq x^2+y^2+z^2[/itex].

Second, is this the entirety of your attempt at the problem? What does this have to do with computing the integral

[tex]\int\int_{\mathcal{S}}\textbf{r}\times d\textbf{S}[/tex]

??

No. We do not provide complete solutions here. It is unethical and it doesn't really help you learn any problem solving skills.

You need to make some effort and show your work in order to receive further help.
