Final answer:
The tire with a radius of 13 inches travels 81.6 inches in one full rotation. To find this, calculate the circumference using the formula C = 2πr and round the result to one decimal place.
Step-by-step explanation:
To find out how far a tire travels every time it turns exactly once, you need to calculate the circumference of the tire. The circumference of a circle (or a tire) is given by the formula C = 2πr, where r is the radius of the circle, and π is Pi, approximately 3.14.
Given that the radius of the tire is 13 inches, the circumference can be calculated as follows:
- First, plug in the values into the formula: C = 2 × 3.14 × 13 inches.
- Next, calculate the product: C = 2 × 3.14 × 13 inches = 81.64 inches.
- Finally, round the answer to one decimal place, which gives us 81.6 inches.
Therefore, every time the tire turns exactly once, it travels 81.6 inches.
