What is pi rounded up to the nearest whole number? Pi is the ratio of a circle's circumference to it's diameter. The resulting number is the reason there cannot be a perfect circle. It's value is approximately 3.142 which, rounded up to the nearest whole number, would be four. It would not be three, as that would be rounding down.

- Pi is an irrational number. A rational number is one that can be expressed as a fraction (or ratio), e.g. 1/3. There are fractions that are near Pi, for example: 22/7 = …3.142857 (PI = 3.14159265...) A closer fraction is: 355/113 = 3.14159292 However whatever fraction you have, you will never get exactly PI.

Mar14 Fun Holiday â Pi Day Pi Approximation Day. Because everyone should be able to enjoy a fun mathematical holiday, people in countries that follow the day/month (dd/m) date format honor pi on Pi Approximation Day. The date of Pi Approximation Day - July 22 - when written in the day/month format or 22/7 corresponds to the fraction (22/7) that pi is usually depicted as. There are many other days during the year when one can honor pi. Some of these are: March 4: The day marks the passing of 14% of the 3rd month of the year.

- The number π is a mathematical constant, the ratio of a circle 's circumference to its diameter, commonly approximated as 3.14159. It has been represented by the Greek letter  π  since the mid-18th century, though it is also sometimes spelled out as  pi  (/paɪ/). Being an irrational number, π cannot be expressed exactly as a fraction (equivalently, its decimal representation never ends and never settles into a permanent repeating pattern).

How to Round to the Nearest Integer | GRE Math Rounding to any other decimal place. Rounding to the nearest integer is really rounding to the nearest units place. Sometimes, you will be asked to round to the nearest hundreds, or to the nearest hundredths — to some decimal place other than the units place. The rule is just a more generalized version of the previous rounding rule.

Rounding whole numbers When rounding to the nearest ten, if the last digit ends with 1, 2, 3, or 4, round to the next number that is smaller than the number given and ending with a zero. For instance, round 43 to the nearest ten.The last digit is 3, so the next number smaller than 43 with an ending of zero is 40.

What is pi? Simple geometry â Math, circles, circumference, diameter 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.

What is Pi? Pi (π), the 16th letter of the Greek alphabet, is used to represent the most widely known mathematical constant. By definition, pi is the ratio of the circumference of a circle to its diameter. In other words, pi equals the circumference divided by the diameter (π = c/d). Conversely, the circumference is equal to pi times the diameter (c = πd). No matter how large or small a circle is, pi will always work out to be the same number. Pi is an irrational number, which means that it is a real number with nonrepeating decimal expansion.

How to Round to the Nearest Integer | GRE Math The result of rounding to the nearest 0.05 would be something divisible by 0.05 — that is to say, a decimal with either a 0 or a 5 in the hundredth place, no digits to the right of that, and any digits to the left of that. The following are examples of numbers which could be the result of rounding to the nearest 0.05:
