draw[line width=0.15cm,red,{Circle}-{Circle},shorten >=-2*pgflinewidth,shorten

node[scale=15.5, red, right, opacity=0.5] at (2,2) {r};

with pdflatex and then convert the resulting pdf with



convert -density 300 -delay 34 -loop 0 -alpha remove outfile.pdf ani.gif

If you wish to produce such animated gifs, you may want to compile



documentclass[border=1cm,tikz]{standalone}
usetikzlibrary{arrows.meta}
begin{document}
foreach X in {180,175,...,90}
{begin{tikzpicture}
begin{scope}
draw (0,0) circle (10cm);
draw[line width=0.15cm, blue] (10,0) arc (0:360:10) ;
draw[-] (-12,0) -- (12,0) node[right] {$x$};
draw[-] (0,-12) -- (0,12) node[above] {$y$};
draw[line width=0.15cm,red,{Circle}-{Circle},shorten >=-2*pgflinewidth,shorten
<=-2*pgflinewidth] (10,0) -- ++(X:10);
node[scale=15.5, red, right, opacity=0.5] at (2,2) {r};
end{scope}
end{tikzpicture}}
end{document}


with pdflatex and then convert the resulting pdf with



convert -density 300 -delay 34 -loop 0 -alpha remove outfile.pdf ani.gif


to get
