Is radius of smaller circle S = 1/3 * (Radius of largest semi circle) ?

I don't know, I don't have the explanation of this question, How you Reach 1/3 please share that.

refer above fig.

In Triangle PRS
OS = R - r
PS = R/2 + r
PO = R/2
(R/2+r)^2 = (R-r)^2 + (R/2)^2
Solving R = 3r
r = (1/3)*R

Great Work , I don't find any problem with your solution , It just seems to be perfect,

Important part was OS = R - r PS = R/2 + r These equations, I was not able to figure out the relation,

Brilliant Man, Really Smart..........
