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.

**Hello Guest!**

\(s=C\cdot n\\ C=2\pi r=2\pi \cdot 14\ in\\ C=87.964\ in \)

\(s=600\ ft\cdot \frac{12\ in}{ft}\\ s=7200\ in\)

\(n=\frac{s}{C}=\frac{7200\ in}{87.964\ in}\)

\(n\approx 82\)

Each tire makes 82 turns.
