Since the center of the circle is at the origin, we can easily figure out that the radius is 16--meaning that the coordinates of point P are (0,16).
Now we just need to find the distance between (0,16) and the given point (-10,-8).
We can use the distance formula (really just the Pythagorean theorem):
\(\sqrt{(-8-16)^2+(-10-0)^2}\)
\(\sqrt{(-24)^2+(-10)^2}\)
\(\sqrt{676}\)=24
Answer: E
