radius x^2+y^2<9

Solution

radius

x^{2} + y^{2} < 9

Solution

r = 3

Solution steps

x^{2} + y^{2} < 9

Rewrite

x^{2} + y^{2} < 9

in the form of the standard circle equation

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

Therefore the circle properties are:

(a, b) = (0, 0), r = 3

And the radius is:

r = 3

Popular Examples

radius 36x^2+36y^2-24x+36y-245=0 radius

36 x^{2} + 36 y^{2} - 24 x + 36 y - 245 = 0

radius x^2+y^2+10x-18y+70=0 radius

x^{2} + y^{2} + 10 x - 18 y + 70 = 0

radius (x-2)^2+y^2=25 radius

(x - 2)^{2} + y^{2} = 25

radius x^2+y^2-4x=5 radius

x^{2} + y^{2} - 4 x = 5

radius x^2+y^2+2x-10y-10=0 radius

x^{2} + y^{2} + 2 x - 10 y - 10 = 0
