The wheel on Kirk's bike has a diameter of 27 inches. How far does the bike travel each time the wheel rotates?

C = pi * d

C = 3.14 * 27
C = 84.78 inches

To find out how far Kirk's bike travels each time the wheel rotates, we need to know the circumference of the wheel. The circumference of a circle can be calculated using the formula C = π * d, where C is the circumference and d is the diameter of the circle.

In this case, the diameter of Kirk's bike wheel is given as 27 inches. So, we can calculate the circumference as follows:

C = π * d
C = π * 27
C ≈ 3.14 * 27
C ≈ 84.78 inches

Therefore, each time the wheel rotates, Kirk's bike travels approximately 84.78 inches.
