Question

The center of the circle is at (-2,-7) and its radius is 36.

What is the equation of the circle in graphing form?
1.) (x+2)^2+(y+7)^2=1296
2.) (x-2)^2+(y-7)^2=6
3.)(x+2)^2+(y+7)^2=6
4.) (x-2)^2+(y-7)^2=1296

Answer 1

standard form for circle with radius r and center (h,k) is
(x-h)^2+(y-k)^2=r^2

r=36
center at -2,-7
(x-(-2))^2+(y-(-7))^2=36^2
(x+2)^2+(y+7)^2=1296
