The Math of Disney

Just returned from a week in the Magic Kingdom, where I learned a lot. Like this tidbit:

A recent government study just confirmed that six of seven dwarves is not Happy.

That’s so good, it deserves a graphic:

I also learned that relativity is a novel concept for kids who are 6 years old. When asked how fast we were traveling on The Barnstormer junior roller coaster, one of my sons replied, “It felt like we were going 100 mph!” The other said it only felt like 50 mph. When asked how fast we were traveling in the airplane on our ride back to Virginia, one son suggested 10 mph, the other suggested 20 mph.

Depressingly, the ratio of bottles of Coke to bottles of water consumed at Disney is almost 6 to 1. According to a Walt Disney World fact sheet, tourists to Disney consume 75 million bottles of Coke and 13 million bottles of water annually. My sincere hope is that most folks use refillable water bottles, which would explain the discrepancy in sales.

And finally a math question.

The fact sheet states that the Earffel Tower, which is the water tower at Disney’s Hollywood Studios, would wear a hat size of 342-3/4, although another reference says that the hat size would be 342-3/8. What is the approximate radius of the Earffel Tower?
