so I'm given two circle equations. once with the center (1,1) and radius 2 and the other with center (5,9) and radius 4 ...

usukidoll · Answer

though I don't think center (5,9) is right? why is the radius so small ont hat one?! Anyway...

usukidoll · Answer

first I draw the cienter and the radius.... along with that point
