figuring out new engine size after you bore out!

[Dchoquette]

i wanted to figure out how to do this for so long and i finaly got it:
boreing a suzuki quadsport 230
0.007854xborexborexstroke (say factory bore is 66mm and your oversized piston is a .75mm piston and factory stroke is 67mm then equation would be=
0.0007854x66.75x66.75x67mm=234.46<--------new engine size

Isn't that the same as Bore/2 squared X Pi X Stroke?
