Bavaro's Basketball team is driving to a game that is 64 km awa from school. Each tire of their van has a radius of 32 cm. They drive at a constant speed for 2 hours.
What distance does one revolution of a tire cover?

To solve for the linear distance, apply the relationship between radius and linear distance which is:
`s = theta r`
Since we have to determine the linear distance in one revolution, then `theta=2pi` .
So, plug-in `theta = 2pi` and r=32 cm.
Hence, `s = 64pi` cm.
Then, convert it to km.
`64pi cm xx (1 m)/(100cm)xx(1km)/(1000m)=0.002 km`
Therefore, the distance travelled by the tire in one revolution is 0.002 km.
