Hi Yaroslav,
a possible solution is to extract the list of points from the PolarPlot
and then draw these points using ListLinePlot with Filling. E.g:
g=Table[PolarPlot[(formula@@v)[x],{x,-Pi,Pi},PlotRange->All,Axes->None],{v,vals}]
ListLinePlot[#[[1,1,3,2,1]],Filling->Axis]&/@g
hope this helps, Daniel
