x^2+(y-7.5)^2= 9/49

x^{2} + (y - 7.5)^{2} = \frac{9}{49}

(a, b) = (0, 7.5), r = \frac{3}{7}

Solution steps

x^{2} + (y - 7.5)^{2} = \frac{9}{49}

Rewrite

x^{2} + (y - 7.5)^{2} = \frac{9}{49}

in the form of the standard circle equation

(x - 0)^{2} + (y - 7.5)^{2} = (\frac{3}{7})^{2}

Therefore the circle properties are:

(a, b) = (0, 7.5), r = \frac{3}{7}

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

x^{2} + y^{2} + 10 x - 4 y - 8 = 0

x^{2} + y^{2} - 4 x - 12 y + 24 = 0

x^{2} + 8 x + y^{2} + 6 y - 11 = 0

4 x^{2} + 20 x + 4 y^{2} - 24 y + 21 = 0
