That is made with this code:



     documentclass{article}

usepackage{amssymb,amsthm,amsmath}
usetikzlibrary{shapes,positioning,intersections,quotes}

begin{center}
begin{tikzpicture}

draw [rotate=270] (-2,0) arc (180:0:1);
draw (0,0) circle (2cm);

filldraw[black] (-1,2.1) circle (0pt)
node[anchor=west] {tiny{$R_1$}};
end{tikzpicture}
end{center}




end{document}


And I want to know if there is a way to color in gray the zone that is between the 2 lines (in both zones). Any ideas? Thanks.

          • Wow, thanks, actually I don't use the polar plots becouse I am just learning to use Tikz. But I will look for it.

          • @J.Rodriguez In this situation they may be very useful. Anyway, I added a second method (clip) in case you do not want to use them.
