Yes its correct you did well :)
The equation of a circle uses the following formula:

The center of the circle is given by (h,k). Therefore, h = -2, and k = -5. r = 1, so we can find the equation from the information given to us.
Plug in your values.


The equation of this circle is as follows:
Answer:
5.507*10^-7%
Step-by-step explanation:
(2.5 * 10^5)/(4.54 * 10^9)*1/100 %= 5.507*10^-7%
add them all up or Mutiply and Divide all together I think
