Do you round decimals of pi?
We don’t need to be concerned here with exactly what the value is (you can multiply it out if you like) but rather what the error in the value is by not using more digits of pi. In other words, by cutting pi off at the 15th decimal point, we would calculate a circumference for that circle that is very slightly off.
Who found the value of pi correct to 4 decimal places?
Archimedes of Syracuse
The representation of Pi takes place by the Greek letter “π” since the mid-18th century. Since Pi was discovered by Archimedes of Syracuse, experts also call it the Archimedes’ constant. He was one of the best Mathematicians in Egypt.

Is it possible to round Pi to 5 decimal places?
Simple answer, yes. Longer answer, when rounding decimal numbers, if the next digit in precision is 5 or higher you round up, if it’s 4 or lower, you round down. When we take Pi to 5 decimal places we have 3.14159…
What does it mean to round to four decimal places?
Given a number with more than four decimal places, in order to “round to four decimal places” you find the *closest* number which has four decimal places. So pi=3.14159265… would be rounded to 3.1416, since this number is clearly closer to pi than 3.1415, or indeed any other number with 4 decimal places (d.p.s).
What is the value of N3 when PI is 5?
Because the value of Area stops at one decimal place it stops at 5, but for pi it returns to 4 decimal places which is the value of n3. # Complete the ‘tria’ function below.
What does it mean to round to 4 in math?
When they say round to four it means to fewer the digits to 4 to the right of the decimal point. The basic rule to remember is, if the number in the 5th place ( to round it any decimal place, consider its next digit) is > 5 then add 1 to the 4th digit or else remains the same.
