radius x^2+y^2=20

radius

x^{2} + y^{2} = 20

r = 20

Solution steps

x^{2} + y^{2} = 20

Rewrite

x^{2} + y^{2} = 20

in the form of the standard circle equation

(x - 0)^{2} + (y - 0)^{2} = (20)^{2}

Therefore the circle properties are:

(a, b) = (0, 0), r = 20

And the radius is:

r = 20

x^{2} + y^{2} - 2 x + 6 y + 9 = 0

y^{2} + x^{2} - 6 y + 5 = 0

x^{2} + (y - 1)^{2} = 4

x^{2} + y^{2} - 2 x + 4 y - 31 = 0

x^{2} + y^{2} + 8 x - 2 y - 19 = 0
