Identify the center and the radius of a circle with equation (x-4)^2+(y+2)^2=9

center:(4,-2)

Radius: 3 units

Step-by-step explanation:

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

The given equation is .

We compare to the standard equation of the circle to get;

and

Hence the center of the circle is (4,-2).

Also, we have

Therefore

units.

283 square feet
