x^2+y^2=2.5

x^{2} + y^{2} = 2.5

(a, b) = (0, 0), r = 1.58113 \dots

Solution steps

x^{2} + y^{2} = 2.5

Rewrite

x^{2} + y^{2} = 2.5

in the form of the standard circle equation

(x - 0)^{2} + (y - 0)^{2} = 1.58113 \dots^{2}

Therefore the circle properties are:

(a, b) = (0, 0), r = 1.58113 \dots

x^{2} + y^{2} + 6 x - 4 y = 387

x^{2} + y^{2} - 2 x + 12 y + 29 = 0

x^{2} + y^{2} - \frac{23}{2} x + \frac{11}{2} y - \frac{13}{2} = 0

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

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