radius x^2+y^2=16

Solution

radius

x^{2} + y^{2} = 16

Solution

r = 4

Solution steps

x^{2} + y^{2} = 16

Rewrite

x^{2} + y^{2} = 16

in the form of the standard circle equation

(x - 0)^{2} + (y - 0)^{2} = 4^{2}

Therefore the circle properties are:

(a, b) = (0, 0), r = 4

And the radius is:

r = 4

Popular Examples

radius x^2+y^2=49 radius

x^{2} + y^{2} = 49

radius (x-6)^2+(y-4)^2-64=0 radius

(x - 6)^{2} + (y - 4)^{2} - 64 = 0

radius x^2+y^2+12x-4y-40=0 radius

x^{2} + y^{2} + 12 x - 4 y - 40 = 0

radius x^2+y^2+4x-6y-3=0 radius

x^{2} + y^{2} + 4 x - 6 y - 3 = 0

radius x^2+4x+10y+y^2-2=0 radius

x^{2} + 4 x + 10 y + y^{2} - 2 = 0
