I love pi. It is so delicious and creamy. I could fall asleep counting pi.
"Hey April this is about math."
"Oh, sorry Bill"
Pi is one of the longest numbers of all. I can remember 3.1415637289 wait or was it 4.31571930. I cant remember.
"April its 3.141592 and so on."
Pi can help you find out the circumference of a circle. Also, it can help you find out the area of a circle. You get the point? Pi is helpful for a lot of things. While finding the area or circumference of a circle you use Pi which is 3.14. Pi goes on forever but for math we just use 3.14. It is easier to use 3.14 than a million numbers. Also, you are going to need to know that this is the symbol for pi, π.
Learning how to use pi is really easy. Today I am going to tell you how to use pi with circles. To use pi with a circle you need a circle with radius or diameter. Once you have it with the numbers the you are ready to go. we are going to be working on circumference. The circumference has to equations. One for radius and one for diameter. The equation for diameter is C=πd and the equation for radius is c=2rπ. In the picture we are doing radius. So the first step is you take the r, which equals 14, and multiply it times 2. You should get 28. After you have multiply by 2 then multiply by 3.14(pi). You will need a calculator for this. I got 87.92 and that is your answer. Don't forget to put what you unit which is miles. Now on to diameter. For diameter there would be a line all the way across the circle with a number above it. In this example the number will be 18. If the formula is c=πd than all you have to do is multiply pi with the diameter. So 18 times 3.14(pi) is 56.52. The unit was feet. The answer for diameter is 56.52 feet. That is how you do circumference with pi.
Math bust time
Can you memorize all the digit of pi?
It is impossible to memorize all the numbers of pi. The post memorized of pi is 70,000."The most decimal places of Pi memorized is 70,000, and was achieved by Rajveer Meena (India) at the VIT University, Vellore, India, on 21 March 2015. Rajveer wore a blindfold throughout the entire recall, which took nearly 10 hours," says
http://www.guinnessworldrecords.com. The most they have found of digits in pi is 2.7 trillion. That is is a lot of digits.
d= diameter symbol
Circumference-the distance around something, Most likely a circle
Area-the measurement of a surface
Radius- a straight line from the center of a circle
Diameter-a straight line passing from side to side through the center of a circle

P.S. Bill wanted me to tell you he helped too.
A happy person who loves doing math problems all day.
