Why are there two formulas to calculate the circumference of a circle?
They are: 2*pi*radius or as diameter*pi
Pi can be used to calculate the blank of a circle?
Pi can be used to calculate the area of a circle Pi can be used to calculate the circumference of a circle
How can pi be found?
Pi= c/dPi equals the circumference of a circle divided by the diameter. If the radius is presented, double the radius to find the diameter.The Wikipedia article in the related link, lists several formulas which have been used to calculate approximations of the number pi.
What does pi the formula in math stands for?
In certain formulas, including most that involve circles, you will see 'pi'. This pi always has the same value, approximately 3.14159... However, this number is irrational, which means it never terminates (ends) or repeats. But what exactly is pi? Pi is the ratio between any circle's circumference and its diameter. This ratio is always the same, no matter how big or small the circle is, but the degree of precision might vary depending on how big the circle is. Why is Pi useful? Pi allows us to calculate the diameter or area of any circle, but also has many other uses. In order to use these formulas, though, we need to define the terms we are using. Circumference - the distance around the circle Diameter - the length of a straight line segment that passes through the center of the circle Radius - the distance from the center of the circle to the circle itself To calculate the circumference, multiply the diameter by pi (3.14...) To calculate the area, square the radius, then multiply this by pi (3.14...) In symbols: Circumference = diameter x pi Area = (radius)2 x pi Hope this helped.
Who was the first mathematician to calculate pi?
The first person to calculate pi was Archimedes, around 250 B.C. Using the formula:A = pi r^2

Where is pi celebrated?
All around the world, because pi is used in many formulas.

Pi can be used to calculate the area of a circle Pi can be used to calculate the circumference of a circle
How many digits of pi did William shanks calculate?
707
How is pi used today?
pi is used in many different formulas. Formula for circumference, Area of a circle, and as we all know, pi is an endless decimal but technically is not repeating

How do you get the math pi?
pi is an irrational number, which if calculated as a decimal, will have an unending sequence of digits which never repeats. You can use 3.14 or the fraction 22/7 as an approximation. There are tables with pi carried out to thousands of digits, as well as formulas to calculate the digits of pi using infinite series. Scientific calculators as well as many spreadsheet software programs have a built-in value for pi, that can be accessed. See related link for more information.
Who is responsible for finding how many digits are in pi?
Nobody is responsible. Different groups have decided, on their own, to calculate pi to many digits - as a sort of challenge.
Is pi in formulas?
Yes. Some examples of formulas that contain pi (∏) are: (area of a circle) = ∏r2 (Circumfrance of a circle) = ∏d
How many decimals does pi calculate into?
Rotate '8' 90 degrees... and there you go.
