Linear mass density of a rod varies as $\lambda =kx$. Among the axes shown, the moment of inertia of the rod is maximum for

Find the moment of inertia of a solid hemisphere of mass $M$ and radius $R$ about $A{A}^{\text{'}}$

A disc of radius $R_1$ is cut out from a disc of radius $R_2$ as shown in figure. If the remaining portion of the disc has mass M then find the moment of inertia of the disc left about an axis passing through its centre and perpendicular to its plane.

Moment of inertia of a ring of radius $R$ whose mass per unit length varies with parametric angle $\theta$ according to relation $\lambda ={\lambda }_0{\cos }^2\theta$, about its axis will be

A solid hemisphere $\left(m,R\right)$ has the moment of inertia about axis $1$ (Diameter of hemisphere)
