(x)^2+(y)^2=49

(x)^{2} + (y)^{2} = 49

(a, b) = (0, 0), r = 7

Solution steps

x^{2} + y^{2} = 49

Rewrite

x^{2} + y^{2} = 49

in the form of the standard circle equation

(x - 0)^{2} + (y - 0)^{2} = 7^{2}

Therefore the circle properties are:

(a, b) = (0, 0), r = 7

y^{2} + z^{2} = 25

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

(x - 5)^{2} + (y - 3)^{2} = 81

x^{2} + 8 x + y^{2} - 9 y = 6

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