What is the difference between 3.14 and the square root of 76

Okay well the squad root of 76 is 8.717 (I only go to the 3rd number behind the decimal) but it needs to be rounded so 7 is more than dive so the won will be come a 2. So now it is 8.72. Now we subtract 3.14 from 8.72. 8.72-3.14 = 5.58. So your answer is 5.58
