center x^2+y^2=21

Solution

center

x^{2} + y^{2} = 21

Solution

(0, 0)

Solution steps

x^{2} + y^{2} = 21

Rewrite

x^{2} + y^{2} = 21

in the form of the standard circle equation

(x - 0)^{2} + (y - 0)^{2} = (21)^{2}

Therefore the circle properties are:

(a, b) = (0, 0), r = 21

And the center is:

(0, 0)

Popular Examples

center x^2+y^2-20x+36y+353=0 center

x^{2} + y^{2} - 20 x + 36 y + 353 = 0

center (x+1)^2+(y-5)^2=4 center

(x + 1)^{2} + (y - 5)^{2} = 4

center (x+1)^2+(y+3)^2=9 center

(x + 1)^{2} + (y + 3)^{2} = 9

center (x-5)^2+(y+1)^2=16 center

(x - 5)^{2} + (y + 1)^{2} = 16

center (x-5)^2+(y+1)^2=12 center

(x - 5)^{2} + (y + 1)^{2} = 12
