Center: 
Radius: 
Step-by-step explanation:
It is necessary to remember that the Equation of the circle in Center-radius form, is:

Where the center of the circle is at the point (h, k) and the radius is "r".
Then, given the following equation of the circle:

We can notice that it is written in Center-radius form. Then we can identify that:

Therefore the center is:

And the radius is:

#22 is Ian. #23.a. is 77%. b. is Yes. c. is 16.
The number of zeros in the product has 5 zeros and the zeros in the factor has 4 zeros because when you multiply 5,00x by8 you get 40,000
