How do I calculate the volume of a circular section of a sphere? Sort of
like what we grind out when hogging. What I want to do is work out how big
a blank I can get from brick of C1 glass (see corning optical glass thread
for details) I'm planning on casting one of the curves into the blank so I
want to work out the volume of the, at this point convex side.

Anyway thoughts and more importantly the formula to do this would be great.

TIA.

Clear skies, Thomas
