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)
$$

1 answer

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.
