Mars and math

Latest Mars photo from the rover.

Math puzzle for the day.
You have a sphere. A cylindrical hole is drilled through the center of the sphere. The length of the hole from end to end is 6 cm. What is the volume of the pierced sphere?

It's wacky... you don't need to know the radius of the sphere or the radius of the hole. Confused? This answer is not likely to help much.
