Answer:
Use the value the problem statement tells you. Otherwise, use a better approximation.
Step-by-step explanation:
π ≈ 3.141592653589793238... (a non-repeating infinite decimal)
3.14 = 3.14
22/7 = 3.142857142857_142857
355/113 = 3.14159292035... (a very long repeating decimal)
You can see that the third decimal place is wrong in both of your approximations. The last approximation shown has 7 good decimal digits. A good scientific or graphing calculator will have an internal value for pi that is good to 10 or 12 digits or more (preferably, at least 32 digits).
You should use a value for pi that has at least one more digit of accuracy than the number of significant digits in your answer.
Answer:
7.01, 10, 7.1, 12, 7.001, 8, 15
Step-by-step explanation:
Those numbers are all greater than 7

Answer:
$8.65×10^3
Step-by-step explanation:
The amount the West raised is the difference between the total and the sum of the other amounts raised. It is convenient to use a multiplier of 10^4 for each of the numbers, so the number for South can be rewritten as 0.675×10^4.
West = 5.38×10^4 -1.46×10^4 -2.38×10^4 -0.675×10^4
= (5.38 -1.46 -2.38 -0.675)×10^4
= 0.865×10^4 = 8.65×10^3
West raised $8.65×10^3.
