if this helps, when calculating the volume i had to solve this: triple-integral{(r from b/Cosθ to R,θ from 0 to ArcCos[b/R],φ from 0 to 2π)r^2 sinθ dr dθ dφ} R = radius, b = R - depth of being

"Yup. And remember to convert z as well" what do you meen?

you meen dV=dz*dy*dx=r^2*sinθ*dr*dθ*dφ ?? Also by a you meen the corner acording to the depth?

I can understand that i am only going to use the z formula. I alsow understand it is going to be a tripl-integral. What i can't find is from where to where am i going to integrat, and what coordinate system would be most suted

ideasrule, i fail to see the difrens between the two integral, also rho=?

Well what i ment is that i need to find the center of mass of each section , A and then B.

A being is on a sphere like planet. Sudently hey grabs a GPS and starts diging straight on a diemeter, heading to the center. We can theoretically say tha he is carrying a level with him. Then tha sphere is theoretically cut in two section , A and B. I have(well...with help) found the volume of...
