To find the most accurate value of pi for calculating the circumference of a circular skating pond, we should consider how closely each provided value approximates the true value of pi (which is approximately 3.14159265358979).
The provided options are:
- 3.14 (approximation: fewer decimal places, less accurate)
- 3.14159 (very close to true pi)
- 22/7 (approximately 3.142857, less accurate)
- 3.1416 (very close, but slightly less than 3.14159)
Among these, 3.14159 is the most accurate value of pi.
