The tires on your bicycle have a radius of 14 inches. How many rotations does each tire make when you travel 900 feet? Round your answer to the nearest whole number ...

Around 150 rotations

I rounded the radius to feet which is 1 foot. Then you have to get the diameter which is 1x2=2. The diameter is 2 feet. Now for the circumference, we multiply 2 by 3.14 (which is pi). The answer to that is 6.28, and since we are rounding it, we get 6 feet. However, we are traveling 900 feet. Divide 900 by 6 and get 150.
