I write the solution ASSUMING THAT YOU KNOW THE BASIC CONCEPT OF YOUNG’S MODULUS
Y=4FL/\Pi d^{2}\Delta L
(\DeltaY)/Y=2(\DeltaD)/D  + \Delta(L)/\DeltaL =0.1125   (SUBSTITUTING THE VALUES)
\DeltaY=2 X 1011 X 0.1125
      =0.2250 X  1011
SO THE ANSWER IS   (2 .0 ± 0.2) × 1011 N/m2  
HOPE you understood,if not then you are free to ask here again.
please approve if you are satisfied.
