7 0

Answer:

10 units

Step-by-step explanation:

Length of the radius of the circle will be equal to the distance between the center of the circle and the point through which it passes.

Therefore,

Length of radius

=  \sqrt{(1 - 7)^{2}  +  {( - 3 - 5)}^{2} }  \\  \\  \sqrt{ {( - 6)}^{2} + ( - 8)^{2} }  \\  \\  =  \sqrt{36 + 64}  \\  \\  =  \sqrt{100}  \\   \\  = 10 \: units
