If `I_(1)` is moment of inertia of a thin rod about an axis perpendicular to its length and passing through its centre and `I_(2)` is its moment of inertia when it is bent into a shape of a ring then (Axis passing through its centre and perpendicular to its plane)

If I_(1) is the moment of inertia of a thin rod about an axis perpendicular to its length and passing through its centre of mas and I_(2) is the moment of inertia of the ring about an axis perpendicular to plane of ring and passing through its centre formed by bending the rod, then

If I_(1) is the moment of inertia of a thin rod about an axis perpendicular to its length and passing through its centre of mass and I_(2) is the moment of inertia of the ring about an axis perpendicular to plane of ring and passing through its centre formed by bending the rod, then

Find the moment of inertia of ring about an axis passing through the centre and perpendicular to its plane.

Calculate the moment of inertia of a ring about in axis passing through centre and perpendicular to its plane.

If I_(1) is the moment of inertia of a thin rod about an axis perpendicular to its length and passing through its centre of mass and I_(2) is the moment of inertia (about central axis) of the ring formed by bending the rod, then the ratio of I_(1) to I_(2) is
