+253 Find an equation of the circle that satisfies the given conditions.
+128732 Let's find the radius....this is given by ...
√[(-2-9)^2 + (10-7)^2] = √[(-11)^2 + 3^2' = √(121+9) = √130
So the "formula" for an equation of a circle is given by
(x-h)^2 + (y-k)^2 = r^2 where, h,k is the center and r is the radius .... so we have...
(x - (-2))^2 + (y-10)^2 = 130
(x +2)^2 + (y-10)^2 = 130
And that's it !!!.....
