Flattened Dimension of an Arc Segment?

Hello,

I am a graphic designer and have a problem. I am designing digitally printed artwork that will be applied to a panel that is already radiused. I need to create an equal border all around, but can not figure this out until I know the what the larger, flat dimension of the radiused panel would be. Attached is the information that I know. Thank you in advance for your help.

Are you asking for the arc length? Get angle in radians $\displaystyle a=\frac{67\frac{2}{3}}{180}\pi $. Arc length = 20.375a.

Thanks for your response mathman. Not the arc length, but the flattened length. I may not be using proper terminology, so I apologize. If you could visualize physically holding the arc segment and and then bending it flat, what would the flat length be? Thank you!

If there is no stretching or shrinking, the flattened length equals the arc length. If it doesn't, then you'll need to define flattened length better.

given the numbers shown the panel needs to be 24.063 inches wide.
