One rotation is equivalent to the circumference of the tire. In other words, if the tire makes one complete rotation and the bicycle has traveled a distance equal to the circumference of the tire.
Solution:
C = 3.1416 which is the pi (d)
C = 3.1416 (27)
C = 84.82
The circumference is about 84.82 inches. To find the distance the bicycle will travel in 10 rotations then multiply the circumference by 10.
84.8 (10) = 848.2
So, the bicycle will travel about 848.2 inches in 10 rotations.
