^yes do that and simplify
Jhannybean
  • Jhannybean

Write the equation of the circle with center (-4, 11) and containing the point (5, -1). since everyone is here could somebody help me with this?
anonymous
  • anonymous
THATS HECTIC
anonymous
  • anonymous
radius of the circle using distance formula
anonymous
  • anonymous
I knoww
anonymous
  • anonymous
I get 15
anonymous
  • anonymous
(x-h)^2+(y-k)^2=r^2
anonymous
  • anonymous
where (h,k) is the centre
anonymous
  • anonymous
okay I know that formula, but what would I plug in?
anonymous
  • anonymous
h=-4 k=11 r^2=15^2
anonymous
  • anonymous
(x+4)^2+(y-11)^2=225
