Math(s) Can be Fun and Useful

Say you want to fence your racetrack most people have in the backyard.
You don't know how much fence you need so make a high side guess for the inside fence.
Then take how much you used and calculate for the outside fence and buy how much more you need. ;)

A more practical instance of the "Belt around the Earth" brain teaser: If you have a belt around the Earth, how much longer would it have to be in order to raise it one foot, all the way around?

Maths can be fun.

Stop that, stoppit rfn!

6.28 feet (1.914144 m).

Nonsense. We all know what the real number is. 42.
