Find the center and radius of the circle whose equation is <img src="https://tex.z-dn.net/?f=x%5E%7B2%7D%20%20%2B%20y%5E%7B2%7D%
LenaWriter [7]

Answer:

the center is (3,1) and the radius is √6.

Step-by-step explanation:

The center of a circle can be found using the equation (x-h)^2 + (y-k)^2 = r^2 and is (h,k) from it. Notice h and k are the opposite value as in the equation.

First write the equation in this form.

x^2 - 6x + ( ?)+ y^2 - 2y + (?) + 4 = 0

Complete the square with each variable to find what numbers should go in place of the question marks.

(-6/2)^2 = -3^2 = 9

(-2/2)^2 = -1^2 = 1

Add 1 and 9 to both sides of the equation.

x^2 - 6x + 9 + y^2 - 2y + 1 + 4 = 1 + 9\\(x-3)^2 + (y-1)^2 + 4 = 10\\(x-3)^2 + (y-1)^2 = 6

So the center is (3,1) and the radius is √6.
