Answer:
(x-3)^2+(y+4)^2=64

Explanation:

The equation of a circle is
(x-h)^2+(y-k)^2=r^2. h and k are the points of the center corresponding with x and y respectively. r is radius. All we have to do is plug the values in.


(x-3)^2+(y-(-4))^2=8^2

With our values plugged in, we can now simplify.


(x-3)^2+(y+4)^2=64

Therefore, our final equation is
(x-3)^2+(y+4)^2=64.
