How to find 'a' ?
I'm not sure what they're expecting from you here. Without additional information, surely there are infinitely-many possible values for "a"...?
You have:. . . . .
Completing the square gives:. . . . .. . . . .. . . . .. . . . .
But without some sort of restrictions on the circle, more information on "a", or something else, I see no way to find "the" value of "a".
Please consult with your instructor, and reply. Thank you!
