Question

Is the given point interior, exterior, or on the circle (x + 2)2 + (y - 3)2 = 81?

Q(3, 0)

Answer 1

is \((3,0)\) more than \(9\) units away from the center \((-2,3)\)?

Answer 2

so on the cricle

Answer 3

Plug (3,0) into the left hand side (LHS) of the equation ... if it is less than 81, then it is inside the circle. If greater, outside. If equal, on the circle.
