Req=(r1)||(r2)

r1=(rho)*R(pi/3)/A

r2=5(r1)

let he resistance of  whole ring i.e. 2ΠR be r.

therefore the resistance of wire between points a and b is r/6

and the reistance of rest part of ring is 5r/6

now these two resistances are in parallel combination

therefore equivalent resistance will be 5r/36....
