Starting with the general form for a circle with center at (h, k) and radius, r.

The center is given as (3, 4) so substitute h = 3 and k = 4.

To find the radius r, the distance from the center to the circumference, you know that the circumference touches the line x = 6, so the radius would be the distance from the center (x = 3) to the line (x = 6) which gives you a radius of 6-3 = 3. Now you can complete the equation:
or
