Question 1b2b20b9

Circle A shown is defined by the equation $x^2+{\left(y-6\right)}^2=7$. Circle B (not shown) has the same radius but is translated $96$ units to the right. If the equation of circle B is ${\left(x-h\right)}^2+{\left(y-k\right)}^2=a$, where $h$, $k$, and $a$ are constants, what is the value of $4a$?
