Question

You want to calculate the circumference of a circular skating pond by multiplying the diameter times pi. Which of the following values of pi will give the most accurate answer: 3.14, 3.14159, 227
, or 3.1416?(1 point)
$$

Answer 1

To determine which value of pi will provide the most accurate circumference calculation, we should look at the precision of each value of pi:

1. **3.14** - This is a rough approximation, rounded to two decimal places.
2. **3.14159** - This value includes five significant figures, making it a more precise representation of pi.
3. **227** - This is not a common approximation for pi and is incorrect. It’s way off from the actual value of pi, which will lead to significant error.
4. **3.1416** - This value includes four significant figures and is a more precise approximation than 3.14 but less precise than 3.14159.

Given these options, **3.14159** is the most accurate value of pi listed, as it is the closest approximation to the true value of pi (approximately 3.141592653589793).

Therefore, the most accurate answer is **3.14159**.
