Final answer:
To find the distance traveled by the unicycle in 20 rotations, you must multiply the circumference of the tire by the number of rotations.
Step-by-step explanation:
To find the distance traveled by the unicycle in 20 rotations, we need to first determine the circumference of the tire. The circumference of a circle is calculated by multiplying its radius by 2π. Therefore, for a tire with a radius of 13 inches, the circumference would be 26π inches. To find the total distance traveled in 20 rotations, we can multiply the circumference by the number of rotations, which in this case is 20. So, the distance traveled would be 20 * 26π inches.
