radius x^2+y^2-10x+2y+17=0

radius

r = 3

Solution steps

x^{2} + y^{2} - 10 x + 2 y + 17 = 0

Rewrite

x^{2} + y^{2} - 10 x + 2 y + 17 = 0

in the form of the standard circle equation

(x - 5)^{2} + (y - (- 1))^{2} = 3^{2}

Therefore the circle properties are:

(a, b) = (5, - 1), r = 3

And the radius is:

r = 3
