Pi is used in many ways today. The simplest way it to find the circumference (the perimeter) of a circle or the area (amount of space inside) of a circle.


Pi always is the same. 3,1416.....


Today is Pi Day in math which is March 14th and the first three digits of pi are 3.14


Today, march 14, is pi day.


pi is greek for the number 3.14292 ect. It came from greek mathematicians thousands of years ago and is still used today


Pi can be used to find a circle, For the circumference-Pi x D, or for the radius Pi x r2


Pi can be used to calculate the area of a circle Pi can be used to calculate the circumference of a circle



Pi was first used by the Babylonians and Egyptians.


You are probably thinking about Rahmanujan. However, he didn't really "create pi" - God created pi. Nor did he discover it, pi was known well before Rahmanujan. What he did do was to find some very efficient formulae to calculate pi to many decimal places - formulae that are still used today.


3.14159265 That Pi? Many people use Pi. I use Pi in my math class.


well pi is used to find the area of a circle A=pi x the radius squared


When was pi first being used approximated?


Pi is used to find area and circumference of a circle.


It is used to find the area of a circle as pi*radius2


The first time the symbol Pi was first used for Pi was in ancient Greece in their numbers. The symbol "π" was number 80 in Greece.


It was 3 and even today we do not know its exact value only that the circumference of a circle divided by its diameter is the value of pi which is an irrational number that can't be expressed as a fraction.


Pythagoras was the 1st person who used the pi symbol first


No, pi is not used to solve a square root problem.


The approximate value of pi used by the ancient Egyptians was 3.16


It never was and they never were because even today no one has discovered the exact value of pi. All the ancients knew about pi is what we know today and that is the circumference of any circle divided by its diameter is equal to pi which is an irrational number whose decimal places are infinite.


Pi is used to find the area and perimeter of a circle and the volume of a sphere, cylinder, and cone. Pi=3.14159265358979323846264338327950288419716939937510582097494459230781640628620899862803482534211706798214808651328230664709384460955058223172535940812848111745028410270193852110555964462294895493038196... That was 200 decimal places of Pi.


They put the value of pi as about 3 but even today we do not know its exact value only that the circumference of a circle divided by its diameter is equal to pi


Pi is used in nearly every branch of math. If you need to do anything with a circle, pi was used to make that circle. Any measurement of a circle, cylinder, sphere, etc involves pi. Pi is incorporated into the GPS. All kinds of things use pi. A fun fact for pi: the actual length of a river compared to the straight distance from source to mouth will yield pi.


Of course Albert Alva Einstein was born today 3/14 132 yrs ago which really is ironic because today is pi day pi =3.14 and today is 3/14
