Question

Is the given point interior, exterior, or on the circle (x + 2)2 + (y - 3)2 = 81? R(6, 3)

Answer 1

Hello,

Answer: interior.

C(-2,3) is the center of the circle
R(6,3)
Let's calculate RC²=(6+2)²+(3-3)²=8²
==>RC=8 and radius= 9
The point R is thus interior of the circle.

Answer 2

I think it is interior
