Answer: [tex]2\sqrt{2}[/tex]
Step-by-step explanation:
The general form of equation of a circle is given by :-
[tex](x-a)^2+(y-b)^2=r^2[/tex] , where r is radius and (a,b) is the center of the circle.
The given equation of circle: [tex](x - 3)^2 + (y - 5)^2 = 8[/tex]
[tex]\Rightarrow\ r^2=8[/tex]
Taking square root on both sides, we get
[tex]\Rightarrow\ r=\sqrt{8}=2\sqrt{2}[/tex]
Hence, the length of the radius for this circle= [tex]2\sqrt{2}[/tex]
