Arrange word “coronaviruspandemic” in circular.

Please show your attempt, so we can see what sort of help you need; we don't just do the work for you.

If you can't even start, then either show your work for a simpler problem about "arranging letters in circular", or ask a specific question about this. (I suspect you mean arranging the letters in a circle rather than in a line - a circular permutation.)
 
If by next step you mean next part, then I suggest that you place the vowels after you place the other letters.
If you mean that you don't know how to continue where you left off, then just calculate 18!/64
