that means that the radius is the square root of 25, which is 5.
And the coordinates of the center are the numbers in the x and y parentheses.
The trick for the coordinates is that you have to flip around the positives and negatives
from what's in the parentheses. Since the circle here has x minus two and
y plus two, the coordinates are positive 2 and negative two.
So our answer is just B.
