I have no homework related question but my teachers have done an absolutely terrible job explaining rounded pi.Could someone explain it plz?

Answer:See below. Step-by-step explanation:The value of π to six decimal places is 3.141 592… Usually, your teacher will ask you to round it to a certain number of decimal places. (a) Rounding to four decimal places This means you should have four digits past the decimal, and you will round the figure in the fifth place. 3.141592… The digit in the fourth place is 5, and the fifth digit is 9 If the digit to be dropped is greater than 5, you drop it  and all the digits to its right, and you round up the number in the fourth place. To four decimal places, π = 3.1416 (b) Rounding to three decimal places This means you should have three digits past the decimal, and you will round the figure in the fourth place. 3.141592… The digit in the third place is 1, and the fourth digit is 5. If the digit to be dropped is 5 followed by non-zero digits, you drop it and round up the number in the third place. To three decimal places, π = 3.142 (c) Rounding to two decimal places This means you should have two digits past the decimal, and you will round the figure in the third place. 3.141519… The digit in the second place is 4, and the third place digit is 1. The digit to be dropped is less than 5, so you drop it and every other digit to the right. To two decimal places, π = 3.14.
