  • Welcome to TeX.SX! Aren't you this user as well? The calligraphy is very similar and the first name is the same. Apr 20, 2019 at 1:27

  • If it was banned it's because you are not using this site as it's meant to be used. This is not a “do my assignment for me” service. We usually relax the rules for new users but you should learn from the answers you get, not keep posting pictures and asking people to do it for you. And trying to do it 3 hours before the deadline is a terrible idea. (It doesn't look like you were banned, though). Apr 20, 2019 at 1:35

    The problem is not the title, is that you are showing no effort and leaving all the work for other people. Now that you got answers to your questions the least you can do is show your appreciation by upvoting and accepting those answers. This post shows how you do that: tex.meta.stackexchange.com/q/1852 Apr 20, 2019 at 1:52

\begin{tikzpicture}[tdplot_main_coords,bullet/.style={circle,fill,inner sep=2pt}]
 \draw[-stealth] (0,0,0) coordinate (O) -- (2.5*\Radius,0,0) node[pos=1.05] {$x$};
 \draw[-stealth] (O) -- (0,2.5*\Radius,0) node[pos=1.05] {$y$};
 \draw[-stealth] (O) -- (0,0,1.25*\Height) node[pos=1.05] {$x$};
 \draw[dashed] plot[variable=\x,domain=\tdplotmainphi:\tdplotmainphi-180,smooth]
 \begin{scope}[canvas is xy plane at z=0]   
  \foreach \X [count=\Y] in {-2/3,-1/3,2/3}
  {\node[bullet,transform shape] (B-\Y) at (\Radius+\Radius*\X,0){};}
  \foreach \Y in {1,2,3}
  {\node[anchor=south] at (B-\Y){\ifnum\Y=3
 \draw[left color=gray,right color=gray!80,middle color=gray!20,fill opacity=0.5]
   -- plot[variable=\x,domain=\tdplotmainphi+180:\tdplotmainphi,smooth]
   ({\Radius+\Radius*cos(\x)},{\Radius*sin(\x)},\Height) -- cycle;
 \begin{scope}[canvas is xy plane at z=\Height] 
  \fill[gray!30] (\Radius,0) circle[radius=\Radius];
  \foreach \X [count=\Y] in {-2/3,-1/3,2/3}
