Equation of a circle is: (x - h)² + (y - k)² = r² ; where (h,k) is the center and r is radius

So, (x - 2)² + y² = 14 has a center at (2,0) and radius of √14 = 3.7416

Answer: r = 3.742

The equation of a circle:

[tex](x-h)^2+(y-k)^2=r^2[/tex]

where

(h, k) - the coordinates of a center

r - the radius

We have:

[tex](x-2)^2+y^2=14\\\\(x-2)^2+(y-0)^2=(\sqrt{14})^2[/tex]

[tex]Answer:\ r=\sqrt{14}\approx3.742[/tex]
