    Moment of inertia of a RING

    Let I=Moment of inertia of a RING about an axis through its centre and perpendicular to its plane

    To find out I Consider a ring of mass M, radius R and centre O.

    Take an elementary portion of the ring of mass dm and length dx. 

    So, $d I=d m \cdot R^2$

    And,

    $
    I=\int d I=\int d m * R^2=R^2 \int d m=M R^2
    $
