Question

Which is the equation of the circle with center (3,-5) and radius 6?
a (x+3)^2+(y-5)^2=36
b (x-3)^2+ (y+5)^2=36
c (x+3)^2+(y-5)^2=6
d (x-3)^2+(y+5)^2=6

Answer 1

your answer would have to be "b"

Answer 2

Thank you.

Answer 3

no problem I had to do a lesson on this a week ago I understand how it feels when your just learning it. the equation for a circle is (x-center point x+y- center point y) =radius squared therefor if the center point is (3,-5) and the radius is 6 (x-3+y+5)=36

Answer 4

Thanks.
