Answer :
Final answer:
The circumference of a tire with a diameter of 25 inches is found using the formula C = π * d, and is approximately 78.5 inches when rounded to the nearest tenth.
Explanation:
The question is asking to find the circumference of a tire that has a diameter of 25 inches.
To calculate the circumference, we can use the formula C = π * d, where C is the circumference and d is the diameter of the circle. Given that π (pi) is approximately 3.14159, we can simply multiply this value by the diameter to find the circumference.
Using the formula and plugging in the given diameter, we get:
C = π * d
C = 3.14159 * 25
C = 78.53975 inches
Therefore, the correct answer to the question, rounded to the nearest tenth, is 78.5 inches (option a).
