Final answer:
The diameter of a circle with a given circumference can be calculated using the formula C = πd.
Step-by-step explanation:
The circumference of a circle can be calculated using the formula C = πd, where C is the circumference and d is the diameter. In this case, we are given that the circumference is 6 inches, so we can set up the equation 6 = πd. To find the value of d, we divide both sides of the equation by π: d = 6/π ≈ 1.91 inches. Therefore, the correct answer is A) 1.91 inches.
