Final answer:
To calculate the circumference of Mark's tricycle tire with a 5-inch diameter, using π as 3.14, the result is 15.7 inches, making option 1 the correct choice.
Step-by-step explanation:
The question is related to finding the circumference of a tricycle tire given the diameter. The formula to calculate the circumference (C) of a circle is C = π × d, where π (Pi) is approximately 3.14 and d is the diameter of the circle. Given that the diameter of Mark's tricycle tire is 5 inches, we can substitute this value into the formula:
C = π × d = 3.14 × 5 inches = 15.7 inches
Therefore, the closest approximation to the circumference of one of the tires is 15.7 inches, which corresponds to option 1.
