Answer:
Circle
Step-by-step explanation:
The given equation is [tex]x^2+y^2=16[/tex]
We know the standard equation of a circle is given by
[tex](x-h)^2+(y-k)^2=r^2[/tex]
Where, (h,k) is the center of the circle and r is the radius.
We can rewrite the given equation in this form
[tex](x-0)^2+(y-0)^2=4^2[/tex]
Hence, the center of the circle is (0,0) and radius is 4.
Thus, the given equation represents a circle.
