### Pi Day, 14 March (pi = 3.141592654)

In 1737, a mathematician named Euler used the symbol for 'pi' to be equal to the ratio of the circumference to the diameter in a circle.

Many mathematicians and math classes celebrate Pi Day every 14th of March. `1:59pm` is a common celebration time; however, the playing should probably occur at `1:59am` instead.

##### Einstein's Birthday

Albert Einstein was born on 14 March 1879 and he died on 18 April 1955.

##### Ultimate Pi Moment

##### Exercises
1. Compute how old Einstein was when he died.
2. Round the value of `pi` (`3.141592654`) to the nearest thousandth.
3. Write the value of `pi` (`3.141592654`) as a mixed number.
4. A bit more ϖ...

```   With respect to a circle:

A = ϖ * R2
C = ϖ * D
C = ϖ * 2 * R

where A is Area, R is radius, D is diameter, C is circumference
```

Pretend circle `foo` has a radius of `5 meters` and circle `farkle` has a diameter of `8 feet`.

5. Compute the circumference of circle `foo`.
6. Compute the area of circle `farkle`.

RoadHacker has been in New Mexico many times. Spring Break 2005 has RoadHacker returning to New Mexico for a four day roadtrip that will approximate `1320 miles` in length. {RoadHacker:: US Hwy-60 and US Hwy-70 Across New Mexico}

RoadHacker has timed the roadtrip so that he will be in eating pie in Pie Town, New Mexico, on Pi Day. There is a chance that RoadHacker will be in Pie Town at 1:59pm, but this is not a must do. { map}
