Slicing 3d Object

Hi people
I am a newbie I need to slice a 3D ball like the sphere in pic2 so it resembles the blueprint in pic 1 keeping the measurements and dimensions.

the red areas in the blueprint need to be sliced away on the 3D sphere model so there’s a flat plane left afterwards or even better it looks like some sort of porthole.

The “sliced off” parts need to be kept as well

any help would be appreciated!

Also how can I transfer those 1:10 scale measurements on the blueprint to the model so that the model dimensions match the prints?

Thanks a mill
