What is the dimension of this?

I assumed 100 radius circle’s center point is on the red line therefore this dimension is 100.

Where is the R100 Circle center point? It could be off to the side or bottom etc.. (with Walter Fetsch ) Drawing doesn't give a positive answer..

Its' really hilarious - You gave the "Correct" answer and my friend Bernie Daraz said what was wanted to hear and he gets the correct answer, now isn't that awesome..... lolol - It's not who ya know, it's who ya.............

To me they all seem to end at a common tangent point, one could assume that for each radius dimension that it would be offset by the difference in the radius values. Though, I would never assume. If this is just a sketching/modeling exercise it wouldn't matter though.
