Is C8H16+CO2-->H20+O2+C4H8 a balanced equation for the complete combustion of cyclooctane (C8H16)?

No, that is not a balanced equation for the complete combustion of cyclooctane.
What you've shown is not any kind of actual reaction.

The balanced equation for the complete combustion of cyclooctane is:
C8H16 + 12 O2 → 8 CO2 + 8 H2O
