Question

Find the center and radius of the circle with equation (x+2)^2+(y+10)2=4. I am stuck, help?

Answer 1

(x+2)^2+(y+10)^2=4

(x - (-2))^2 + (y - (10))^2 = 4

(x- (-2))^ + (y-10))^2 =???

Answer 2

(x- (-2))^2 + (y- (-10))^2 = (2)^2
so if I'm not wrong results will be:
C=(−2,−10)
r=2

Answer 3

annnas is right. Just look up equation of a circle

Answer 4

wonderful, thanks guys

Answer 5

Kittykitty you are smart :D

Answer 6

(x-h)^2+(y-k)^2=r^2
centre is (h,k) and radius =r.

Answer 7

O.O
