The formula with the Cosines is obviously correct but it is based on the radius of the sphere, not the radius of the dome where it contacts the piston so it will be harder to apply.
Regardless, John and the web site link provided the dome volume making any calculations unnecessary.

: Sorry, try that formula again
:
: Volume= (Pi x R^3)/3 x [2 -
: 3xCos(angle) + Cos (angle)^3]
