**How to calculate length of arc? Please Help!**

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 A-Level.

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!
