Is pi an integer??????? Pi is an irrational number-- 3.14159265.... and on and on forever. An integer is a whole number like 3 or 5 or 8. If you had to express pi as an integer it would be 3 (pi rounded to a whole number), but it would no longer be pi. synaphon · 9 years ago. 3. Thumbs up. 0. Thumbs down.

What is Pi? In basic mathematics, pi is used to find area and circumference of a circle. Pi is used to find area by multiplying the radius squared times pi, or. So in trying to find the area of a circle with a radius of 3 centimeters, π3 2 = 28.27 cm.i is an irrational number, which means that it is a real number with nonrepeating decimal expansion. It cannot be represented by an integer ratio and goes on forever, otherwise known as an infinite decimal. There is no exact value, seeing as the number does not end.

What Makes Pi So Special? Defined as the ratio of the circumference of a circle to its diameter, pi, or in symbol form, π, seems a simple enough concept. But it turns out to be an irrational number, meaning its exact value is inherently unknowable.

What does pi equal? Pi is the ratio of a circle's circumference to it's diameter. It's useful for working out various things about a circle. For example, Where R is the radius of a circle and D is the Diameter (D = 2R), piRSquared will give you the area and piD gives the circumference.

Pi Pi (or π) is a mathematical constant. It is the ratio of the distance around a circle to the circle's diameter. This produces a number, and that number is always the same. However, the number is rather strange. The number starts 3.142857....... and continues without end. Numbers like this are called irrational numbers.

Exhaust Gas Temperatures? One of the variables is exhaust gas temperature. I have never had an opportunity to check exhaust gas temp but I know most of you run gauges on your sleds. What would be a typical range to expect and does the type of fuel have any impact of the temperature. I am sure fuel/air mix ratio will but again, I would be curious to see what would be typical. Thanks.

Pi ( Ï) The distance half way around the circle is 3.14159265... a number known as Pi. Or draw a circle with a diameter (all the way across the circle) of 1. Then the circumference (all the way around the circle) is Pi. So Pi (the symbol is the Greek letter π) is: The ratio of the Circumference.

What is pi? Simple geometry â Math, circles, circumference, diameter Quatr.us > Math > Geometry > Circles > Pi. May 2016 - Pi is a number that is approximately equal to 3.14. It is the number you get if you divide the circumference of any circle by its diameter. It's the same for all circles. You can approximate pi for yourself by taking some circular things like the tops of jars and CD's and frisbees and measuring their diameter and their circumference.

Pi The symbol used by mathematicians to represent the ratio of a circle's circumference to its diameter is the lowercase Greek letter π, sometimes spelled out as pi, and derived from the first letter of the Greek word perimetros, meaning circumference. In English, π is pronounced as pie ( /paɪ/, paɪ).

Swimming Pool Drain Cost 1 Draining and refilling, then adding new chemicals will refresh the water in an otherwise undamaged pool. 2  Costs for refilling a pool will vary, but the average water agency charges about $1-$1.50 per 1,000 gallons, so water for a 20,000 gallon pool would be $20-$30. If you drain and refill your pool, you'll need to add appropriate chemicals to the new water. 2  The cost will depend on your pool size and type of filtering system, but generally runs $15-$50.

What does the math term PI mean or what is it? Pi is always the same number, no matter which circle you use to compute it. For the sake of usefulness people often need to approximate pi. For many purposes you can use 3.14159, which is really pretty good, but if you want a better approximation you can use a computer to get it. Here's pi to many more digits: 3.14159265358979323846. The area of a circle is pi times the square of the length of the radius, or pi r squared: A very brief history of pi. Pi is a very old number. We know that the Egyptians and the Babylonians knew about the existence of the constant ratio pi, although they didn't know its value nearly as well as we do today.

- Well, to calculate pi, we must first understand what it is. Pi is the ratio between the diameter of a circle and the circumference. If you can accurately measure the circumference of a circle (or circle-like shape), and divide it by the diameter, you can get pi accurate to quote a few decimal places.

Is  [math]\pi [/math] equal to 22/7? The value of pi is the ratio of the circumference of a circle to its diameter. Therefore, you can determine the value of pi by drawing ANY perfect circle (either physically or in a computer program simulation), then measure it's circumference and diameter, take the ratio and that's it! The value of pi correct to seven decimal places is: 3.1415926.

Why Is the Greek Letter Pi the Symbol for That Mathematical Ratio Anyway? Pi is the English spelling of the sixteenth letter of the Greek alphabet. This means that the outside measurement of a circle is a little more than three times its width, a ratio that is one of the most important constants in mathematics.
