Nawaryi - We'll be glad to help after you show us what you think the answer is, and why. You might first start by thinking about how many ways 9 people coud be arranged in a line, and then whether placing them in a circle reduces that number. Specifically consider whether when people are placed at a round table is there a head seat of the table that is distinguished from the others?
