Given that Mars has a polar diameter of 6752 kilometers, and the Mars Reconnaissance Orbiter comes as close to the planet as 255 kilometers at the south pole and 320 kilometers at the north pole, how far does MRO travel in one orbit? (JPL advises, "MRO's orbit is near enough to circular that the formulas for circles can be used.")
23,018 km

Our school's puzzle club meets in one of the classrooms every Friday after school.
Last Friday, one of the members said, "I've hidden a list of numbers in this envelope that add up to the number of this room." A girl said, "That's obviously not enough information to determine the number of the room. If you told us the number of numbers in the envelope and their product, would that be enough to work them all out?"
He (after scribbling for some time): "No." She (after scribbling for some more time): "Well, at least I've worked out their product."
Room #12 (The numbers in the envelope are either: 6222 or 4431, which both add up to 12 and the product is 48.)
