Hi I'm new to this forum,tried to do a search but the wording is complicated.

Anyway I'm trying to find a formula or if there is a mathematical way

of finding this answer.

I have a bowl that is 36" in diameter. It is 2" deep at the center.

If I were to cut it into 8 sections(pies) and layed them flat the

long sides of the pies would have a curve to them.How do I find

that curve?Is there an equation that tells you the distance from the curved line on the flat to the straight line when in a sphere?How do I find the length

of the new curved line?Any help would be appreciated.I need to create

a bowl out of flat pieces of paper.Hope I made my question clear without

any diagrams.
