Question

The wheels on a bike have a diameter of 26 inches. How many full revolutions will the wheels need to make to travel 100 feet?​

Answer 1

Explanation:

distance traveled by one revolution = circumference of the wheel

= 2πr = 2π(13 inches) = 26π inches

number of revolutions = distance traveled / distance traveled by one revolution

100 feet = 1200 inches

= 1200 inches / 26π inches

≈ 45.91 full revolutions
