Answer:
Hey there!
First, we want to find the radius of the circle, which equals the length of line segment AC.
Length of line segment AC, which we can find with the distance formula: 
, which is equal to 5.
The equation for a circle, is: 
, where (h, k) is the center of the circle, and r is the radius.
Although I don't know the center of the circle, I can tell you that it is either choice B or D, because the radius, 5, squared, is 25.
Hope this helps :) (And let me know if you edit the question)

He owed $47 to the bank from withdrawing more than he had.
However, he got his paycheck, and it was $598.73
Before he can save, he has to pay back his amount.
-47 + 598.73 is the same as 598.73 - 47
Subtract:
598.73 - 47 = 551.73
