Question

A wheel on Aldo's bicycle is 1.1 ft in diameter. Aldo races the bicycle for 110 ft . How many times does the wheel turn as the bicycle travels this distance? Use the value 3.14 for π . Round your answer to the nearest tenth. Do not round any intermediate steps.

Answer 1

circumference = PI x Diameter

circumference of tire = 3.14 x 1.1 = 3.454 feet

 so every full turn of the tire the bike travels 3.454 feet

110 feet / 3.454 =  31.8 turns
