Divide by PI and you have the diameter increase. Divide that by 2 and you have the radius increase.

Assuming you have an 11T smallest cog, can you actually spin a 40T ring?
Well, that wasn't the OP's question, but that isn't really that big of a gear (smaller than the 52x13 back in the day). I can easily spin out a 42x11, and I'm not a spring chicken.
