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
