Pi is a very popular number in the world of mathematics. We most often learn about Pi when we begin studying geometry, to be more specific, circles. The number is most commonly seen as the decimal, 3.14159 or the symbol, π. We define Pi as the ratio of a circles circumference to its diameter. The circumference is the distance around the whole circle and the diameter is the distance from one edge of the circle to the other edge, right through the center. All though Pi is a number, many people contributed to discovering it, there are a few number of ways we are able to use it, and there are many intriguing facts about it. Pi is an irrational number and has an infinite amount of numbers beyond the right side of the decimal. It is expressed as …show more content…
To calculate the circumference of a circle, we multiply either the radius or the diameter by the pi, C=2 πr or C= πd. The radius is half of the diameter, so when using the radius you must first multiply it by two and then by pi. If you are using a calculator, you can simply do this by typing in the diameter and then the pi symbol. The symbol in the calculator automatically rounds pi to eleven decimal places. If you are trying to find the circumference by hand, you will need to round 3.14159 to 3.14 and then proceed to multiply by the diameter. To determine the area of a circle, you must find the radius. After you find the radius, you multiply it by itself, or take the number and put it to the power of two. The final step is to plug that number into the equation and multiply it by pi, A=πr^2. As said before, if you are using a calculator you simply push the pi symbol during your calculation or if doing it by hand, you must round pi to 3.14. Finally to determine the volume of a cylinder, you must find the height of the cylinder and the radius. Once you find the radius, you need to once again multiply it by itself. After you find these two numbers, you can then plug it into a simple equation like area and circumference, V=h πr². You first multiply the height by pi and then by the number we got when we multiplied the radius by itself. Like the others, when using the calculator, …show more content…
First, only thirty-nine numbers from the right side of the decimal point are needed to calculate the spherical volume of our entire universe. Second, there is a whole day dedicated to pi, known as National Pi Day. March 14th is the day we celebrate Pi, this day was chosen due to it being the 3rd month of the year and the 14th day of the month. This is significant because the first three numbers of pi are 3.14. Third, all digits of pi will never be fully known, which encourages scientists every day to see how far they are able to calculate. (Sylte, 2015) Finally, an approximate ratio also appears in the Bible, in 1 Kings 7:23: “And he made a molten sea, ten cubits from the one brim to the other: it was round all about, and his height was five cubits: and a line of thirty cubits did compass it round about.” (Hengeveld,

As Pi is an active disciple of three separate religions, one would assume he has a shifting opinion on reality and it’s roots. Despite seeing himself as a practicing Hindu, Christian, and Muslim, he believes that there is a unity of all things. This contradicts
In the case of using trigonometry to work out the height of the eucalyptus tree, we only need to use the tangent ratio in our formula because we have length of adjacent and we need to find the opposite length and the tangent ratio is opposite/hypotenuse. The formula itself is; Tan(θ) x adjacent = opposite.
The toothpaste tube is made up of four cylinders. So to find the volume of the toothpaste tube you would need to find the volume of each cylinder and plus them together. To find the volume of the cylinders you need to times pi by the radius2 by the height or the length (π x r2 x h or l). Then once these four volumes had been found and plus together, you would find the volume of the toothpaste tube.
After the calculation we needed to convert pc to meters so we used the calculation factor of 1pc=3*10^16m
Volume = Length - (2 * Cut Out) * Width - (2 * Cut Out) * Height
Pi was teased in school, because his birthname was Piscine Molitor Pate. Since Piscine sounds like “pissing” he was teased and humiliated at school, therefore he decided to change his name to Pi. Pi is a man of many religions. Pi’s first religion was Hinduism, because of his natural love of its spirituality and beauty. Shortly after becoming a Hindu Pi finds himself in a Catholic church, where he falls in love with the story of Christ.
Pi, short for Piscine, meaning a rational source of water, is a rational man living in the irrational world, who believes in not one, but three religions, which some may say is irrational. Pi, whose family owned a zoo, faced many hardships
Students can get the formulas and example problems online. In this article, we shall see how to calculate the volume and surface area of three dimensional shapes. Online 3 dimensional shapes lesson help – Formulas. Cube: What is the difference between cube Volume of the cube (v) = 3 cubic units.
Pi is an indian, but except Hinduism, he also believes in Christianity and Islam. It is pretty unusual. However, these three religions save his life when he meets storm on the sea. Religion is a key component in Pi’s survival because it lets him understand that he has to coexist with other creatures, it leads Pi to accept that even if he did not survive he would be redeemed, and it gives Pi the hope for survival.
To start off, pi is the ratio of a circle’s circumference to its diameter (Bennet, Burton, & Nelson, 2012). This is approximately equal to 3.14159. In equation form it is calculated like this: π = C/d (Shell, 2013). Pi is also an irrational and transcendental number. This means that it will continue infinitely without any repetition or pattern. It also cannot be expressed accurately as a fraction and the decimal never ends (Shell, 2013).
In addition, when Pi is in university and is introducing himself to each of his classes he uses repetition to explain his name. He says his name, writes it on the board, and underlines it. Pi uses ritual to get people in the habit of calling him Pi. This has significance to his past zoo life. Zoo animals need lots of care, this includes feedings, cleanings, and training. Pi is used to ritual, he knows that animals learn/live off of routine, and repetition, and so he has applied these skills to his classmates indicating a similarity between animals, and humans. Animals learn off of repetition, and routine, as do humans. Pi 's name has a mathematical link which has major symbolism to the entire novel. We all know that Pi is a large, and complicated number. Pi says in the novel, "That 's one thing I hate about my nickname, the way that number runs on forever." (Martel 316). I feel like the author included this quote to signify that Pi has been on a long journey, just like Pi says the numbers continue on. This quote was said towards the ending of the novel, and could represent the
Irrational numbers are real numbers that cannot be written as a simple fraction or a whole number. For example, irrational numbers can be included in the category of √2, e, Π, Φ, and many more. The √2 is equal to 1.4142. e is equal to 2.718. Π is equal to 3.1415. Φ is equal to 1.6180. None of these numbers are “pretty” numbers. Their decimal places keep going and do not end. There is no pattern to the numbers of the decimal places. They are all random numbers that make up the one irrational number. The concept of irrational numbers took many years and many people to discover and prove (I.P., 1997).
