I believe you are asking in how many ways they can sit. If so:
The 1st can sit anywhere: he has only 1 way to sit
The 2nd can sit in 11 ways, since one seat is already occupied
The 3rd can sit in 10 ways, since 2 seat are already occupied
The 4th can sit in 9 ways, since 3 seat are already occupied
The 5th can sit in 8 ways, since 4 seat are already occupied
--------------------------------------------------------------------------------
The 12th can sit in 1 way, since11 seat are already occupied
General formula for a circular table:
Number of ways they n persons can be seated: (n-1)!
and the 12 can be seated in (12-1)! = 11! = 39,916,800 ways.
This is called circular permutation

Answer:
C
Step-by-step explanation:
The volume of the cone can be calculated using formula
![V=\dfrac{1}{3}\cdot \pi r^2 h,](https://tex.z-dn.net/?f=V%3D%5Cdfrac%7B1%7D%7B3%7D%5Ccdot%20%5Cpi%20r%5E2%20h%2C)
where h is the height of the cone, r is the base radius.
In your case, h=24 un., r=7 un. So
![V=\dfrac{1}{3}\cdot \pi \cdot 7^2\cdot 24=49\cdot 8\pi=392\pi \ un^3.](https://tex.z-dn.net/?f=V%3D%5Cdfrac%7B1%7D%7B3%7D%5Ccdot%20%5Cpi%20%5Ccdot%207%5E2%5Ccdot%2024%3D49%5Ccdot%208%5Cpi%3D392%5Cpi%20%5C%20un%5E3.)
