How did pi get its symbol What is the reason for having assigned the symbol for pi?
The 'symbol' is a letter in the Greek alphabet - which is pronounced 'pi'. The connection between the letter and the ratio of the diameter and the circumference fo a circle may come from the fact that the letter pi is the first letter of the Greek word for perimeter, and the word for periphery.
What is the perimetre off the cicle?
Perimeter is another word for 'Circumference'. The equation to find the circumference is C = 2pir or C = pi*d Where d = 2r & r = radius d = diameter pi = 3.141592..... ~ 3.14
What is pie in circle?
Firstly the word is pi. It is a Greek letter. In mathematics it is often useful to use letters to represent something unknown. We often use the letter x or the letter n to do so. In certain special cases we keep a letter and that represents something so we all know what we are referring to. In this case, pi. Pi refers to the ratio of the diameter of a circle to its circumference. It is always the same. No matter what size the circle the diameter will always be a certain size compared to the circumference. It is often useful to keep and use such letters and phrases. It is a kind of shorthand for people that use mathematics.
Why do we use the name pi?
The earliest known use of the Greek letter π to represent the ratio of a circle's circumference to its diameter was by Welsh mathematician William Jones in his 1706. It has been speculated that pi was chosen because it is the first letter in the word "periphery." It caught on after being popularized by Euler in 1736.
What does the word pi come from in greek?
It is the 16th letter of the Greek alphabet. In mathematics it is the ratio of the circumference of a circle to its diameter

What part of speech is the word diameter?
The word diameter is a noun. It is any straight line between two points on the circumference of a circle ensuring it passes through the center of the circle.
What is the part of speech for the word diameter?
The word "diameter" is a noun. It refers to a straight line passing through the center of a circle or sphere that connects two points on the circumference.
Are ratios always rational?
No, but the reverse is true. All rational numbers are ratios but not all ratios are rational. You will often come across π being defined as the RATIO of the circumference of a circle to its diameter (there are other definitions). However, the word "rational" is derived from "ratio".
What was radius circumference and diameter named after?
Radius is from the Latin word for a spoke (or rod) from the hub to the rim of a wheel. Circumference is from the Latin word circumferentia, meaning circum (around) and ferre (to carry). Diameter has evolved from the Greek dia- (through) and metron (a measure).
Who came up eith the word pi?
The ratio of a circle's circumference to its diameter, roughly 3.1416, is denoted in science and math by a symbol called 'pi'. The symbol is the 16th letter in the Greek alphabet.
What do the numbers mean in pi?
Pi is the word we use to define the ratio of the circumference of a circle to the diameter. The actual number is called an irrational number because it cannot be expressed exactly as a fraction. Nor can it be expressed exactly as a decimal so we use an approximation. The most often used approximations are 22/7, as a fraction, and 3.14 as a decimal. This is accurate enough for everyday use. So using these numbers, if we know the diameter we can calculate the circumference, or if we know the circumference we can calculate the diameter. (Incidentally it has many other uses too.) For instance, if a circle has a diameter of 10 units (inches, centimetres, miles, any unit), then my multiplying this number by Pi we know the circumference is 3.14 times larger than the diameter or 31.4 of the same units. This also works in reverse, if we know the circle has a circumference of 10 units we divide by Pi to find the diameter.
What does the mathematical symbol for pi mean?
"Pi" is the ratio between the circumference and the diameter of a circle. The Greek letter π (pi) was first adopted for the number as an abbreviation of the Greek word for perimeter (περίμετρος), or as an abbreviation for "periphery/diameter", by William Jones in 1706.

What is the perimeter of a circle with a diameter of 34.5 cm?
Perimeter of a circle actually has a different word for it which is circumference. Since the formula for circumference is 2 pi r, it will be 34.5pi as the radius is half the diameter. *however this is in the form of pi. If pi was in 3.14, then the answer would be 106.33
