Math Wiz Needed !

Anyone know how to calculate cc's from piston/bore diameter?
Stock pistons are 74mm and we have 598.4cc
How many cc's would you get with 79mm pistons which have the same piston shaped top?
Stroke is 69.6mm
Miles

680 cc or 42 cubic inches

I'm not a math wiz but I think this is the answer.
Bore x Stroke x number of cylinders equals cubic capacity.
The shape of the top of the piston will not alter the cc but will effect the compression ratio.
