Answer:

[tex]2\sqrt{2}[/tex] is the exact answer

2.83 is the answer to the nearest 100th

Step-by-step explanation:

I think the equation should be

(x-5)^2 + (y+7)^2 = 8 instead of (x-5)^2 + 4+7)^2 = 8

[tex]r^{2}[/tex] = 8

r = [tex]\sqrt{8} = 2\sqrt{2}[/tex]

[tex]2\sqrt{2}[/tex] is the exact answer

2.83 is the answer to the nearest 100th
