When you drive, your tires don’t wear out evenly; your front tires usually wear out faster than your rear tires. To extend the life of your tires, it is suggested that you switch the front and back tires every 10,000 miles. How many times do your tires complete a full rotation before you should switch your front and back tires? Here are the diameters of the tires of three different vehicles. Calculate their circumferences, rounding to the nearest tenth.

Car tire 17” in diameter:

Bike tire 26” in diameter:

School Bus 19.5” in diameter:

Determine the number of full rotations the tires of each of the vehicles will complete in 10,000 miles, rounding to the nearest tenth.
