We don’t have your requested question, but here is a suggested video that might help.

Two circular loop $A \& B$ of radius $r_{A}$ and $r_{B}$ respectively are made from a uniform wire. The ratio of their moment of inertia about axes passing through their centres and perpendicular to their planes is $\left(\mathrm{I}_{\mathrm{B}} / \mathrm{I}_{\mathrm{A}}\right)=8$ then $\left(\mathrm{r}_{\mathrm{B}} / \mathrm{r}_{\mathrm{A}}\right)$ Ra is equal to... $\{\mathrm{A}\} 2$ $\{B\} 4$ \{C $\}$ $\{\mathrm{D}\} 8$
