![]() ![]() shows that similar discoveries were being made in ancient Egypt. According to the Exploratorium in San Francisco, pi was discovered to be 3.125 on a tablet that was created between 19 B.C. Pi was discovered by the ancient Babylonians and has been around for around 4,000 years. Pi (π) is the name of the well-known mathematical constant and is represented by the 16th letter of the Greek alphabet, which is. Pi always equals the same number, regardless of how big or tiny a circle is. On the other hand, a circle’s circumference is equal to pi times its diameter (c = d). Pi is defined as the circumference divided by the diameter (c/d), in other words. The ratio of a circle’s circumference to its diameter is known as pi. i is an irrational number since it cannot be expressed as the ratio of any two numbers. As a result, 22/7 is used in common calculations. It is well known that pi is an irrational number, meaning that the decimal place is followed by an infinite amount of digits, making pi a non-terminating value. Pi is a mathematical constant that can be written as 3.14 in decimal form or 22/7 in fractions. Since its value is constant, it is referred to as a mathematical constant. In mathematics, the symbol for pi is represented by the Greek letter. Remember that the ratio of a circle’s circumference to its diameter will always be the same, regardless of the size of the circle.įigure 2 – Value of irrational number pi Pi’s Symbol ![]() The answer is roughly 3.14 when we divide the diameter by the circumference. Now, pi is defined as the total number of times the circle’s circumference is wrapped around its diameter or roughly 3.14 times. Imagine that a portion of the circle’s circumference is covered by the diameter line after it has been bent. The ratio of a circle’s circumference to its diameter is known mathematically as “Pi.” The longest line segment that traverses the center of a circle is understood to be the diameter of the circle. It is incorporated into numerous formulas to evaluate the surface area and volume of several solid shapes. It is an irrational number that is typically rounded to 3.14. Since “pi” has a constant value, it cannot be altered. Pi Day, a fictitious festival celebrated annually on March 14 (3/14), is a day when calculations like this are frequently revealed. The value of pi has been estimated by certain computer algorithms to an amazing 62.8 trillion digits. According to the Pi World Ranking List, Suresh Kumar Sharma of India holds the record for reciting pi to the most decimal places, reaching 70,030 in 2015. (These rational expressions only have a few decimal places of accuracy.)Ĭalculating pi to as many digits as feasible is of interest to mathematicians and math aficionados. Although pi is an irrational number, some individuals estimate it using rational formulae like 22/7 or 333/106. Pi is typically introduced to students as having a rough value of 3.14 or 3.14159. ![]()
