Question

Let C be the circle..

Answer 1

i realize that after graphing the circle and the point, that the answer is d. however, i'd like to know if there's a way i can figure that out without having to graph?

Answer 2

i tried putting the point into the equation... like (10 - 1)^2 + (10 - 2)^2, and i got 145...does that mean anything?

Answer 3

Answer 4

145 > 144
I think that means that point P is outside circle C

Answer 5

so if it was exactly 144, then it would be on the circle? and less than 144, it would be inside?

Answer 6

yes!

Answer 7

sorry, i was wrong about that :P

Answer 8

I was about to say ;)

Answer 9

\(\sf (x-h)^2 + (y-k)^2 = r^2\)

(h,k) is the center of the circle. r is the radius of the circle.
