JE pistons and compression

Ok I just got my set of new pistons. I was wondering if anyone new how i could figure out what compression these pistons are. I ordered them to be 12.0:1 compression but they look very dished. they gave me the dome hieght, pin diameter, bore size and everything.

I was wondering if anyone knew how I could figure out the compression with these data. Like some kind of formula or something. They didnt give me a spec sheet this is why im asking. Thanks for help

If you ordered them from JE there is a small chance they are wrong. But anything is possible, 12:1 pistons shouldn't have a dish in them except for where the valve goes.
