    Answer: 5040ways

    Step-by-step explanation:

    This is a circular permutation question. Arrangement of objects in a circular path is (n-1) ! where n is the amount of object. Since there are 8 students sitting in a circle excluding their teacher, they can sit in (8-1) ! ways i. e 7! ways

    7! = 7*6*5*4*3*2*1

    7! = 5040ways

    This means the students can sit in a circle in 5,040 ways
