I think that was the important part of Mike's hint.
Something like -
Plot circles and remember centres and radius
mycentres[n] = xxx
myradius[n] = rrr
next circle, increment n
Test on click by looping through circles ...
For each [n]
Test if clicked point is within myradius[n] from mycentres[n]
If yes, alert ('circle' + n + 'clicked')
Take care about whether you are working in pixels or lat/longs
