Question

Thank you for your help! The question is what is the center and radius of the circle. (x+2)^2+y^2=64. Thank you so much.

Answer 1

If your equation is written in the form
(x-h)^2 + (y-k)^2 = r^2 , the centre is (h,k) and the radius is r

Your equation is written in that form and the centre and radius can be seen as is.
Let me know what you got.

Answer 2

Yup. That is what I got reiny. :) Thanks again.

Answer 3

ok, so my final answer is h=2, k=0, r^2=64, then r=8, is this right?
