On a text book I find a question about circumference. Here is the question:
A hamster runs for 10 hours each night on a hamster wheel that is a 17-centimeter diameter and that the hamster rotates the wheel at a rate of about 25 rotations per minute. Determine how many kilometers the hamster can run in one night.
Could you please help me to find out the answer?

The circumference is 17cm x pi = 53.38 cm
10 hours x 60 mins/hour x 25 rotations/min x 53.38 cm/rotation x 1km/100000cm = 8.01 km
