radius X^2+Y^2=49

Solution

radius

X^{2} + Y^{2} = 49

Solution

r = 7

Solution steps

X^{2} + Y^{2} = 49

Rewrite

X^{2} + Y^{2} = 49

in the form of the standard circle equation

(X - 0)^{2} + (Y - 0)^{2} = 7^{2}

Therefore the circle properties are:

(a, b) = (0, 0), r = 7

And the radius is:

r = 7

Popular Examples

radius x^2+(y-2)^2=36 radius

x^{2} + (y - 2)^{2} = 36

radius x^2+y^2<= 25 radius

x^{2} + y^{2} \leq 25

radius (x+6)^2+(y-7)^2=81 radius

(x + 6)^{2} + (y - 7)^{2} = 81

radius x^2+(y+2)^2=7 radius

x^{2} + (y + 2)^{2} = 7

radius x^2+y^2+7x-2y-1=0 radius

x^{2} + y^{2} + 7 x - 2 y - 1 = 0
