radius (x-1)^2+(y-3)^2=49

radius

(x - 1)^{2} + (y - 3)^{2} = 49

r = 7

Solution steps

(x - 1)^{2} + (y - 3)^{2} = 49

Rewrite

(x - 1)^{2} + (y - 3)^{2} = 49

in the form of the standard circle equation

(x - 1)^{2} + (y - 3)^{2} = 7^{2}

Therefore the circle properties are:

(a, b) = (1, 3), r = 7

And the radius is:

r = 7

364 + 28 y + y^{2} + x^{2} = - 26 x

(x - 6)^{2} + (y - 4)^{2} = 25

x^{2} + y^{2} + 6 x - 2 y - 8 = 0

x^{2} + y^{2} + 2 x + 4 y - 20 = 0

(x - 2)^{2} + (y - 5)^{2} = 9
