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
