3d Sphere to 2d Paper "Slices" Template Tool? (Round Nosecones)

Greetings all...I am always fascinated with paper models in how the modeler is able to turn a 3 dimensional object and render it into 2d. Simple ask - is there an online tool where I can input my variables for a 3d hemisphere (half a sphere) and it spits out "orange slices" so that I can print it out on paper and assemble it as a rounded nosecone?

Here is an example tool for making transitions: https://www.delorie.com/rockets/transitions.html (I'm hoping for something similar, but for making hemispheres.)

Thank you....

I believe you are looking for a hemispherical gore calculator...quick google search found this https://www.ict.griffith.edu.au/anthony/kites/parafauna/chute_design/ there are others out there, also there are manual ways to lay it out...

Yes, thank you for that link/reference. I didn't know what the technical term was for what I was looking to accomplish. I had also come across a research paper that went into this far more in depth. I am actually looking to fiberglass a round foam core and wanted to transfer the paper pattern to the fiberglass cloth so there is minimal overlap on seams when I begin the layup of fiber over the foam core. I was unable to find a simple online tool where the calculations are performed on the back end, but on the front end a few dimensions are entered and "presto" a printable PDF or pattern is ready. There are many ways to do things manually. The finished product, however, is subject to the skill of the craftsman. Using your reference I'll see if I can do something on paper first. Many thanks.

I saw a technique used in costume making where they would cover the shape in aluminum foil then apply a layer of masking tape over the foil. Then they could cut the resulting form until it was flat and then trace it onto the cloth or foam rubber. Here's a similar technique using plastic wrap and duct tape;https://www.instructables.com/id/Cast-or-Pattern-Anything-with-Duct-tape/step2/Protect/

Below is the layout I use for making my 8 gore hemi chutes.
