A thin uniform rod of mass M and Length ...

A thin uniform rod of mass `M` and Length `L` has its moment of inertia `I_(1)` about its perpendicular bisector. The rod is bend in the form of a semocircular arc. Now its moment of inertia through the centre of the semi circular arc and perpendicular to its plane is `I_(2)`. The ratio of `I_(2) : I_(2)` will be ____.
