y^2=81-x^2

Solution

y^{2} = 81 - x^{2}

Solution

(a, b) = (0, 0), r = 9

Solution steps

y^{2} = 81 - x^{2}

Rewrite

y^{2} = 81 - x^{2}

in the form of the standard circle equation

(x - 0)^{2} + (y - 0)^{2} = 9^{2}

Therefore the circle properties are:

(a, b) = (0, 0), r = 9

Popular Examples

(x-0)^2+(y-8)^2=5^2

(x - 0)^{2} + (y - 8)^{2} = 5^{2}

(x - 5)^{2} + y^{2} = 12

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

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

x^2+6x+y^2-6y=-9

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

(x+iy-1)((x-iy)-1)=4(x+iy+1)(x-iy+1)

(x + i y - 1) ((x - i y) - 1) = 4 (x + i y + 1) (x - i y + 1)
