bobs bike tire has a radius of 16 inches. how many inches does the wheel travel when it makes one full revolution?
118.32
100.48

Step1: Recuerda la fórmula de la circunferencia.
La circunferencia de un círculo es $C = 2\pi r$, donde $r$ es el radio.
Step2: Sustituye el valor del radio.
Dado que $r = 16$ pulgadas y tomando $\pi\approx3.14$, entonces $C=2\times3.14\times16$.
$C = 6.28\times16=100.48$ pulgadas.
