To solve this question, we have to find the equation of the circle with given center and where it passes. Doing this, we get that the equation of the circle is:

Equation of a circle:
The equation of a circle with center
and radius r is given by:

Center at (16, 30)
This means that 
Thus

Passes through the origin:
We use this to find the radius squared, as this means that
is part of the circle. Thus



Thus, the equation of the circle is:
