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

radius

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

r = 1

Solution steps

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

Rewrite

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

in the form of the standard circle equation

(x - 1)^{2} + (y - 0)^{2} = 1^{2}

Therefore the circle properties are:

(a, b) = (1, 0), r = 1

And the radius is:

r = 1

2 x^{2} + 2 y^{2} = 50

x^{2} + y^{2} = 7

\frac{x ^{2}}{49} + \frac{y ^{2}}{49} = 1

16 x^{2} + 16 y^{2} + 96 x - 40 y = 315

x^{2} + y^{2} + 6 x - 4 y + 3 = 0
