Hi every body. I want sketch a cylinder inside a sphere, I use the following command from ... -with-tikz.

coordinate (O) at (0,0,0)
coordinate (I) at  (0,0,2)
coordinate (A') at  (0,\r,4)
coordinate (A) at  (0,\r,0);
\coordinate (B) at ($(O) + (\d:{2*sqrt(3)} and \r)$);
\coordinate (B') at ($(B)+(0,0,4)$);
\coordinate (O') at ($(O)+(0,0,4)$);
\draw[dashed] (A)--(A') (B) --(B') (O)--(O') (O)--(A) (I) --(A);
\foreach \v/\position in {I/left,O/below,O'/above,A/below,B/below,A'/left,B'/left} {
    \draw[draw =black, fill=black] (\v) circle (1.2pt) node [\position=0.2mm] {$\v$};
\begin{scope}[tdplot_screen_coords, on background layer]
\fill[ball color=orange!70, opacity=1.0] (I) circle (\R);
\tkzMarkRightAngle[size = 0.3](I,O,A);
\draw [thick] (B) arc (\d:90:\r);
\draw [thick, dashed] (A) arc (90:310:\r);
\draw [thick] (B') arc (\d:90:\r);
\draw [thick, dashed] (A') arc (90:310:\r);

I don't want A, B, A',B', ..., appear in it.
I want the shape to be like this picture.
with respect
