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, 22/7

Question

, or 3.1416?

Answer 1

To determine which value of pi will give the most accurate answer for calculating the circumference of a circular skating pond, we can compare the values:

1. 3.14 - This is a rough approximation of pi.
2. 3.14159 - This value is a more precise approximation of pi, accurate to 5 decimal places.
3. 22/7 - This is a common fractional approximation of pi, which is approximately 3.142857. While it's close, it is not as precise as 3.14159.
4. 3.1416 - This is also a good approximation of pi, accurate to 4 decimal places.

Among these options, 3.14159 is the most accurate value of pi, as it is the most precise representation available in the choices given. Therefore, using 3.14159 will give you the most accurate answer for calculating the circumference.
