7x^2+7y^2=91

7 x^{2} + 7 y^{2} = 91

(a, b) = (0, 0), r = 13

Solution steps

7 x^{2} + 7 y^{2} = 91

Rewrite

7 x^{2} + 7 y^{2} = 91

in the form of the standard circle equation

(x - 0)^{2} + (y - 0)^{2} = (13)^{2}

Therefore the circle properties are:

(a, b) = (0, 0), r = 13

x^{2} + y^{2} - 6 x + 8 y + 21 = 0

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

x^{2} + y^{2} - 2 x - 4 y + 4 \leq 0

x^{2} + y^{2} + 6 x - 18 y + 25 = 0

5 = ((x + 1)^{2} + (y - (- 5))^{2})^{2}
