Question

A circle is centered at C(−1,−3) and has a radius of 6.Where does the point P(-6,-6) lie?

A. Inside the circle

B. on the circle

C. outside the circle

Answer 1

Check the distance "\(\Delta\)" from C to P:

\(\Delta^2 = (-6 -(- 1))^2 + (-6 -(- 3))^2\)

\( = 25 + 9 = 34 \)

Whereas \(R^2 = 36\)
