You can put this solution on YOUR website! an circle is centered at the point (-3,2) and has a radius of length 7. what is the equation?
.
Since the standard circle equation is:
(x-h)^2 + (y-k)^2 = r^2
where
(h,k) is the center
r is the radius
.
mapping what was given we have:
(x-(-3))^2 + (y-2)^2 = 7^2
(x+3)^2 + (y-2)^2 = 7^2
(x+3)^2 + (y-2)^2 = 49
