Given:
A graph have circle drawn on it.
Required:
Write Standard equation of circle.
Explanation:
We know the standard equation of circle is
[tex](x-h)^2+(y-k)^2=r^2[/tex]Where, (h, k ) is center of circle and r is radius.
Now,
From graph we can see that Center is (-3, 0) and radius is 7.
So,
[tex]\begin{gathered} (x-(-3))^2+(y-0)^2=7^2 \\ (x+3)^2+y^2=49 \end{gathered}[/tex]Answer:
Hence, option A is correct.
