您能告诉我如何修改下面的代码，以便我可以为六边形周围的部分添加阴影吗（附图）？
非常感谢

你可以使用even odd rule它。我还删除了所有不必要的包和行。
\documentclass[]{article}
\usepackage[margin=0.5in]{geometry}
\usepackage{tikz}
\begin{document}
\begin{tikzpicture}
\newdimen\R
\R=1.7cm
\draw[thick] (0:\R)
\foreach \x in {60,120,...,360} { -- (\x:\R) };
\fill[black,thick] (0,0) circle (0.4mm);
\draw[black,thick] (0,0) circle (1.7cm);
\fill[yellow,even odd rule] (0:\R)
\foreach \x in {60,120,...,360} { -- (\x:\R) } (0,0) circle (1.7cm);
\draw [thick](0,0) -- (+0.84,1.48);
\draw [thick](0,0) -- (-0.84,1.48);
\node[above,scale=0.9] at (0,0.4) {$60^{\circ}$};
\end{tikzpicture}

只是为了完整性：与 的输出相同shapes.geometric。
\documentclass[tikz,border=3.14mm]{standalone}
\usetikzlibrary{shapes.geometric}
\begin{document}
\begin{tikzpicture}
\newdimen\R
\R=1.7cm
\node[regular polygon, regular polygon sides=6, draw,thick,
minimum width={2*\R}] (hexagon) {};
\fill[black,thick] (0,0) circle (0.4mm);
\draw[black,thick] (0,0) circle (1.7cm);
\fill[yellow,even odd rule] (0:\R)
\foreach \X in {1,...,6} { -- (hexagon.corner \X) } (0,0) circle (1.7cm);
\draw [thick] (hexagon.corner 1) -- (0,0) -- (hexagon.corner 2);
\node[above,scale=0.9] at (0,0.4) {$60^{\circ}$};
\end{tikzpicture}
\end{document}
