Best ResponseYou've already chosen the best response.0The radius is half of the diameter. So the first step is to halve the diameters of both circles.

Best ResponseYou've already chosen the best response.0Well it seems that they want you to simplify. It would look like this \[\large \frac{6x}{3x\sqrt{3}}\]

Best ResponseYou've already chosen the best response.0So can you simplify that?
