Approximation for pi?
3.142 rounded to 3 decimal places
When finding area of circle in millimeters is Pi still 3.14?
3.14 is always the best 3 digit approximation of pi.
How do you explain pi in geometry?
By definition, pi is the ratio of the circumference of a circle to its diameter. Pi is always the same number, no matter which circle you use to compute it. For the sake of usefulness people often need to approximate pi. For many purposes you can use 3.14159, which is really pretty good, but if you want a better approximation you can use a computer to get it. Here's pi to many more digits: 3.14159265358979323846. The area of a circle is pi times the square of the length of the radius, or "pi r squared": A = pi*r^2
When Circumference is 60 inches - what is diameter?
In order to find the diameter of a circle, you have to take the circumference of the circle and divide by Pi for which you can use the approximation: 3.14. So if the circumference of the circle is 60 inches, you divide that by Pi (3.14) and get a diameter of 19.0985 inches.
What is the area of a circle that has a radius of 3 miles?
Area of a circle formula: pi*radius^2 (pi multipled by (radius squared)) Pi is a number with an infinite number of decimal places, it is on most good calculators (the symbol looks a bit like a bridge, or something from Stone Henge). If you can't find the function for pi on your calculator, use the approximation pi=3.14159. So, Area=3.14159 multiplied by 3^2.
What is an approximation of pi?
Think of pi as infinity. It never ends. You might mean "3.14" as an approximation of pi, though.
What is the fractional equivalent of the approximation of pi?
That depends on how precise you want the approximation.
Why value of pi is considered 227?
22/7=3.14286 Which is a fair approximation to Pi, but 355/113 =3.14159 and is a much better approximation.
What mathematical principle is equal to 3.14?

Why is a fraction an approximation for pi?
It is: 22/7
What is equal to 3.1415?
That is an approximation of the number pi.
To find a diameter of a circle multiply circumference by 0.31831?
Yes. That's a decimal approximation of 1 over pi.
What is the word for 3.14?
Pi, although it is only an approximation
Is pi 22 over 7?
It is an approximation, yes.
What is the entire decimal approximation for pi?
To have an "entire approximation" in itself is an oxymoron. We have to approximate pi because you cannot express the true value of pi as a decimal. It goes on forever. This is an invalid question. Pi is generally approximated, however, as 22/7 or 3.14.
What approximation of pi was used by the egyptians?
The approximate value of pi used by the ancient Egyptians was 3.16
What is the Chinese fraction approximation of pi?
pi=355/113 http://www.pidayinternational.org/Pi_History/HISTORY_OF_PI_Ancient_China.htm
