Little mathematics problem

I am a little confused by the use of the term "cirumference around the curve was 0.86m." Do you mean the distance between the same two opposite edges as measured along the curved surface is 0.86 Meters?

You want to know if you flattened this curved piece of metal out flat, what would be the distance between opposite edges now measured along the flat surface?

Would this not be 0.86 Meters?

To make this shield one would take a piece of metal 0.86 meters wide and bend it with a constant radius until the arch formed would measure 0.66 meters across the void between opposite edges.

Or does "cirumference around the curve" mean the circumference of the virtual circle if the material of the shield were extended to make a complete cylinder of the same constant radius?

That does not seem right as the diameter of such a cylinder would be only 0.27 Meters in diameter which is pretty small for a shield.

I guess I am stubbing my eye on "cirumference around the curve".

I just reached the same conclusion now that I thought about it.
