Question

What is the center and radius of the circle with equation (x + 9)2 + (y + 5)2 = 64?

center (9, 5); radius = 64
center (5, 9); radius = 8
center (-9, -5); radius = 64
center (-9, -5); radius = 8

Answer 1

standard form equation of circle is \[\huge\rm(x-\color{red}{h})^2+(y-\color{ReD}{k})^2= \color{blue}{r}^2\]
where (h,k) is the center point and r is radius
