Question
The chain wheel of Emma's bicycle has a radius of 3.5 inches. The rear gear has a radius of 1.75 inches, and the back tire has a radius of 12 inches. If Emma pedals for 150 revolutions of the chain wheel, how far will she travel? Round to the nearest foot.(IMAGE CAN'T COPY).
Step 1
The angular speed in radians is given by the formula $\omega = n \times 2\pi$, where $n$ is the number of revolutions. In this case, $n = 150$ revolutions. So, we have: \[\omega = 150 \times 2\pi = 942.5 \, \text{radians}\] Show more…
