The circumference of a circular disk is approximately 67.23 centimeters. The diameter of the disk is 21.4 centimeters.
Which ratio best represents the value of 𝜋?
The ratio that best represents the value of 𝜋 is the ratio of the circumference to the diameter of the disk.
Using the formula for the circumference of a circle, which is C = πd (where C is the circumference, π is the value of 𝜋, and d is the diameter), we can substitute the given values to get:
67.23 = π(21.4)
Dividing both sides by 21.4:
π = 67.23 / 21.4
π ≈ 3.14
Therefore, the best ratio representing the value of 𝜋 is 3.14.
