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 over 7 , or 3.1416?

Answer 1

To determine which value of pi will give the most accurate calculation of the circumference, we can consider each value's approximation of pi and how close it is to the actual value of pi, which is approximately 3.14159.

1. 3.14 - This is a common approximation but less accurate than the true value.
2. 3.14159 - This is the most precise representation of pi in this list, as it is rounded to five decimal places.
3. 22 over 7 (approximately 3.142857) - This is a well-known fraction that approximates pi, but it is less accurate than 3.14159.
4. 3.1416 - This is a rounded approximation of pi but is slightly less accurate than 3.14159 (it rounds to four decimal places).

Among these options, the best choice for the most accurate value of pi is 3.14159.
