Identify the radius and the center of a circle whose equation is (x - 5)2 + y2 = 81.
the radius of the circle is
the center of the circle is at (1
units.

The center is (5,0) and r=9.

Step-by-step explanation:

The standard form of a circle is where (h,k) is the center and r is the radius.

On comparing your equation of

, we should see that h=5,k=0, and r=9.

The center is (5,0) and r=9.

The center is at (5,0) and the radius is 9

Step-by-step explanation:

(x - 5)^2 + y^2 = 81.

An equation for a circle can be written in the form

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

Where (h,k) is the center and r is the radius

Rewriting the equation

(x - 5)^2 + y^2 = 81.

(x - 5)^2 + (y-0)^2 = 9^2

The center is at (5,0) and the radius is 9
