The correct graph of the circle [tex]\rm x^2+y^2=9[/tex] is graph D, the corrcet option is D.
What is the equation of the circle?
A circle can be represented as;
[tex]\rm (x-h)^2+(y-k)^2=r^2[/tex]
Where h and k are the centers of the circle and r is the radius of the circle.
The given equation of the circle is;
[tex]\rm x^2+y^2=9[/tex]
Here the center of the circle h = 0 and k = 0 so the circle passes through the origin.
The radius of the circle is;
[tex]\rm r^2=9\\\\r^2=3^2\\\\r=3[/tex]
Hence, the correct graph of the circle [tex]\rm x^2+y^2=9[/tex] is graph D, the correct option is D.
