81=x^2+y^2

Solution

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

Solution

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

Solution steps

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

Rewrite

81 = x^{2} + y^{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^2+(y^2))/(36)=1

\frac{x ^{2} + ( y ^{2} )}{36} = 1

2x^2+16x+2y^2+14y=-77/2

2 x^{2} + 16 x + 2 y^{2} + 14 y = - \frac{77}{2}

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

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

x^2+y^2-4y-15=6

x^{2} + y^{2} - 4 y - 15 = 6

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

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