Answer:

(x-5)^2+(y-2)^2=9\\

Step-by-step explanation:

So, you basically want the equation of the circle.

Given:

Center(C): C(5, 2)

r=3

The equation of circle is:

(x-h)^2+(y-k)^2=r^2\\

Where, (h, k) represents the center point and r is the radius of the circle.

Plotting the values in the equation:

(x-5)^2+(y-2)^2=3^2\\

(x-5)^2+(y-2)^2=9\\

This is the equation of the circle of center (5, 2) and radius 3.
