EXPLANATION
The equation of a circle with center (h,k) and radius r is the following:
[tex](x-h)^2+(y-k)^2=r^2[/tex]
In this case, the center is at (5,0) and the radius is diameter/2=8/2=4
Therefore, the equation is as follows:
[tex](x-5)^2+(y-0)^2=4^2[/tex]
Computing the power:
[tex](x-5)^2+y^2=16\text{ \lbrack EQUATION OF THE CIRCLE\rbrack}[/tex]
The solution is:
(x-5)^2 + (y-0)^2 = 16
The graph is the following:
