I thought one solution but the questions of previous post still
remains

In[9]:=
halfspa = Block[{$DisplayFunction = Identity},
ParametricPlot[13*{Cos[u], Sin[u]}, {u, Pi, 2*Pi}, PlotStyle ->
Thickness[0.008],
     PlotPoints -> 100]];
halfspagr = halfspa /. Line[x_] :> {GrayLevel[0.95], Polygon[x]};

In[13]:=
Show[{halfspagr, halfspa}, Axes -> None]

Thanks
Dimitris
