What is the radius for the circle given by the equation? ( gmanyp)

The equation of a circle:

where

(h, k) - the coordinates of a center

r - the radius

We have:

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

r = 3.742

i'm sure goog can you get that answer
