Step-by-step explanation:
We know that if (h,k) is the center of any circle and whose radius is = r then its equation is :

Given, the equation of circle

By comparing, we will get,
h = -2
k = 3
So, center of the circle is ( -2,3)

Answer: 60 of the patients are boys.

160.
= 60
Per month, 60 boys have appointments at the medical office.
