We have, redius (R) =0.2 m and density `(p)=8xx10^(3)kg//m^(2)`

Moment of inertia about the tangent to its surface,

`I=I_(C)+MR^(2)`

[ using parallel axis theorem]

`(2)/(5)MR^(2)+MR^(2)`

`=(7)/(5)MR^(2)" "......(i)`

But, Mass (M) =Volume (V)`xx` Density (p)

`M=V_(p)=((4)/(3)piR^(3))p`

Putting the value of M ing (i), we get

`I=(7)/(5)((4)/(3)piR^(3))pR^(2)`

`=(28)/(15)piR^(5)p`

`=(28)/(15)xx3.142xx(2xx10^(-1))^(5)xx8000`
