a^2+b^2=81

Solution

a^{2} + b^{2} = 81

Solution

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

Solution steps

a^{2} + b^{2} = 81

Rewrite

a^{2} + b^{2} = 81

in the form of the standard circle equation

(a - 0)^{2} + (b - 0)^{2} = 9^{2}

Therefore the circle properties are:

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

Popular Examples

x^2+y^2+520x+160y+202=0

x^{2} + y^{2} + 520 x + 160 y + 202 = 0

2x^2+2y^2+20x+8y+40=0

2 x^{2} + 2 y^{2} + 20 x + 8 y + 40 = 0

(x-(-1))^2+(y-4)^2=2^2

(x - (- 1))^{2} + (y - 4)^{2} = 2^{2}

solvefor x,x^2-6x+Y(x)^2+4Y=36 solve for

x, x^{2} - 6 x + Y (x)^{2} + 4 Y = 36

((y-2)^2+(x+1/2)^2)/9 =1

\frac{( y - 2 ) ^{2} + ( x + \frac{1}{2} ) ^{2}}{9} = 1
