True.

The equation of a circle is (x-k)^2 + (y-k)^2 = r^2

h and k represent the center, since the center is at the origin, h and k would 0 and 0

Any value of x or y minus 0 would be x or y, simplifying the equation to x^2 +y^2

As for the 16, since the radius is 4, 4^2 is equal to 16, making the equation valid.

Hopefully, this was somewhat helpful.
