Don't know about more accurately but I could have put it better.
Total volume equals swept volume plus combustion chamber.
Swept volume is 3199 cc (Calculated from bore and stroke comes to 3199.184?)
If you divide 3199 by 9 (one less than compression ratio) you get 355.444 cc for the volume left at TDC which I know as the combustion area.
To check it (3199 + 355.444) / 355.4 = 10.00011 ie 10:1
