After playing around on Desmos for a bit, I'm unsure if I can see if a circle with a radius of 1/2 will fit this circumstance. Are you sure this is the right answer? Also, since a=1, this can't possibly be right, since there are no circles that can go through (1,1) with radius 1/2, or yet even other any radius!
