B 4.6 inches4.6 inches
C 5.1 inches5.1 inches
D 6.3 inches
To find the circumference of the miniature tire, we can use the formula C = πd, where C is the circumference and d is the diameter.
C = π * 1.468 inches
Using the approximation π ≈ 3.14, we can calculate the circumference:
C ≈ 3.14 * 1.468 inches
C ≈ 4.60632 inches
Rounded to the nearest tenth, the circumference of the miniature tire is approximately 4.6 inches.
Therefore, the correct answer is B) 4.6 inches.
