From a uniform wire, two circular loops are made (i) 
of radius 
and (ii) 
of radius 
. If the moment of inertia of 
about an axis passing through its centre and perpendicular to its plane is 8 times that of 
about a similar axis, the value of 
is (diameter of the wire is very much smaller than 
or 
)
