Given a circle with a center at (-3.1) and a radius of 4, is the point (1,-2) inside,
outside or on? Show all work for your proof.

Respuesta :

Answer:

Step-by-step explanation:

distance between center and (1,-2) is

[tex]d=\sqrt{(1-(-3))^2+(-2-1)^2} \\=\sqrt{16+9} \\=5>4\\[/tex]

distance of the point from the center>radius of circle.

So it lies outside the circle.
