Question 74160: I have a poster project due in the next 48 hours all of it is on the term "pi" I can't really think of any examples of pi. I have to have 7 of them can you help? Also I have to have at least 4 example problems.

Here are some applications from people.bath.ac.uk/ma3mju/uses.html

* Pi can be used to calculate the area and perimeter of a circle, or any other shape involving circles
* Pi is used in hundreds of scienific calculations, some of which include;
1. Describing DNA
2. A rainbow
3. Ripples from rain drops
4. Einstein's Gravitational Feild Equation
5. Waves
* Testing the accuracy of super computers
* Cryptography - the science of coding
* Generation of a Random Number
*Pi appears in one of the most fascinating formulae in history; Euler's famous equation 'eip + 1 = 0', which connects constants e, i (sqrt%28-1%29) and pi
*Checking for accuracy - as there are now millions upon millions of known decimal places of pi, by asking a super computer to compute this many figures its accuracy can be tested
*Calculating field strength - it is included in Einstein's Gravitational Field Equation
*Calculation of time period, T, in Simple Harmonic Motion - 'T = 2p sqrt%28m%2Fk%29' (used to find harmonic frequency of an object-physics application)
*Determining the distribution of primes - the probability that two randomly selected integers are relatively prime (ie have no common factors) is 6 /pi2

This is just some of the many applications of pi. You can google more if you like so you can find equations and problems that are solved by pi.
