How to measure radius of arc in sketchup

Can someone explain how I can measure the radius’ of the curved portions of this table top? Or better yet just do it for me and give me the #sketchup

Thank you!

In future add the .skp file not the .dae.
The long edge is 4m the short 1m or to be closer to exact, 4.202 and 0.982.
It’s basically a 4:1 table.
