Answer:

Step-by-step explanation:

8! = 40,320.

The round table implies we are interested in relative order. So if one person sits down, there are 8 choices who sits to their immediate left. Then 7 choices who sits to that person's immediate left. Then 6… etc.

Alternatively, you could say there are 9! absolute seating arrangements, but for any arrangement there are 9 rotations that are equivalent in terms of relative order. So that's 9/9 = 8
