I need help with the question below. A bicyle tire has a diameter of 24 inches. If a tire rotates for 20 revolutions about how far has the bike rider ridden? Use 3.14 for pi. I know to find the circumference you would do 24 x 3.14 which equal 75.36. I'm not sure what to do with the number of revolutions though. Do you multiply 75.36 times 20? Thanks
