What is $\rm cl([-2,2]\times[-3,3])$ in this topology

62 Views Asked by At

I have this topology on $\mathbb{R}^2$, $$\sigma=\{\emptyset\}\cup\big\{\bigcup_{r\in A} \Omega_r:~A\subseteq \mathbb{R}^+\big\}$$

where $$\Omega_{r}=\{(x,y)\in\mathbb{R}^2: x^2+y^2=r^2\}$$

I want to find $\rm cl(A)$ where $A=[-2,2]\times[-3,3]$

Is $$\rm cl(A)=\Omega_{\sqrt{13}}$$ or $$\rm cl(A)=\bigcup_{0\leq r\leq \sqrt{13}}\Omega_r$$

Thank you very much
