First of all, Hi, I'm Brandon! :) 18 Years old currently doing A Levels  Uni End of this year!
(Not Homework  Coursework!) So I have this design of a speaker system for my Product Design course in ALevel. There are 3 arcs in my design that I need to know the length of for when my school orders the materials to my specific measurements. Here is a picture with measurements of my design from SolidWorks CAD Software. The arc at the top is 100mm high and the side arcs would be 50mm All measurements in mm. I hope this is enough info for you to help me!

So you know the radius of a circular arc and you know the length of a chord of that arc.
Can you draw a right triangle anywhere?

does solidworks cad have a function to tell you the length by selecting the arcs of interest?
THis link seems to imply that: http://grabcad.com/questions/howto...dworksdrawing and here at solidworks cad site: https://forum.solidworks.com/thread/60322

Thank you very much guys, sorted!
