Question 682035: it says sketch the circles,identify the center and radius of each.
x^2 + (y-4)^2=64
(x+3)^2 + (y+6)^2= 49
thank you

You can put this solution on YOUR website!
x^2 + (y-4)^2=64

(x-0)^2 + (y-4)^2=8^2

So the center is (0,4) and the radius is 8 units

Sketch:




===========================================================================

(x+3)^2 + (y+6)^2= 49

(x-(-3))^2 + (y-(-6))^2= 7^2

Center: (-3, -6)

Radius: 7 units

Sketch:
