The equation of the circle is always:
[tex](x - h)^{2} + (y-k)^{2} = r^{2}[/tex]
Where (h, k) is the center of the circle, r is the radius. So, the equation will be:
[tex]x^{2} + y^{2} = 64[/tex]
Hope this helps! The answer is B.

Answer: B

Step-by-step explanation: The equation would be x^2+y^2=64 or 8^2
