a
We are given that a bicycle has tires with a diameter of 24 inches, and we want to find the circumference of a tire. Let's recall that the circumference of a circle is the product of its diameter and pi.
C=π d= 24π≈ 75.4
The circumference of the tire is approximately 75.4 inches.
b
In this part we want to find how many inches the tire will travel after 100 rotations. To do this we need to multiply the circumference of one tire, which is approximately 75.4 inches, by the number of rotations.
100* 75.4=7540
The tire will travel approximately 7540 inches.
