Here's one simple-minded way:  Evaluate the input cell:

   Table[Show[Graphics[
      Circle[{0, 0}, {1, t}], AspectRatio -> Automatic]],
      {t, 0.1, 1, 0.1}];

This will produce a whole table of graphics display cells.

Now:

1. select the cell bracket enclosing the entire group of those display 
cells. (You may collapse the entire group if you wish, but be sure that 
one of the cells, say the first one, is visible on screen.)

2.  From the Cell menu select Animate Selected Graphics (or use the 
shortcut key equivalent, e.g., Ctrl-Y is Windows).

I said "simple-minded" above because this way necessitates manual 
intervention.  There are fancy ways to have the graphic display cell 
group close automatically and be animated automatically.  But it wasn't 
clear from your question how fancy you wanted to get.
