Question

A hamster runs in its wheel whose radius is 3 inches. The wheel completes 6.3 revolutions in 5 seconds.

What is the linear velocity of the hamster's wheel?


approximately 3.8 inches per second

approximately 7.6 inches per second

approximately 23.8 inches per second

approximately 66 inches per second

Answer 1

approximately 23.8 inches per second

Explanation:

Be careful about what you multiply in this problem.

6.3/5 = 1.26. 1.26*2π = 7.9169. 7.916813*3 = 23.750. (rounded it will equal 23.8)
