Answer:

5 units

Step-by-step explanation:

Center of the circle = (-3, 2)

Point on the circle = (1, 5)

Radius of the circle will be equal to the distance between the points (-3, 2) & (1, 5)

\therefore \: radius \: of \: the \: circle \\  =  \sqrt{ {( - 3 - 1)}^{2} +  {(2 - 5)}^{2}  }  \\  =  \sqrt{ {( - 4)}^{2}  +  {( - 3)}^{2} }  \\  =  \sqrt{16 + 9}  \\  =  \sqrt{25}  \\  \therefore \: radius \: of \: the \: circle  = 5 \: units
