Question

A small hamster wheel has a radius of 4.5 inches. A large hamster wheel has a radius of 6 inches. In one revolution, how much farther will the large hamster wheel turn than the small hamster wheel? Round your answer to the nearest tenth of an inch.

Answer 1

Volume small wheel = 4/3×pie×4.5^3
= 381.7035

Volume large wheel = 4/3×pie×6^3
= 904.7787

How much further = 904.7787 - 381.7035
= 523.08 in^3

Answer 2

It would be the difference in their circumferences.

So, Circumference of Large hamster wheel = 2 * 3.14 * 6 = 37.68 in

Circumference of small hamster wheel = 2 * 3.14 * 4.5 = 28.26 in.

Difference = 37.68 - 28.26 = 9.42

In short, Your Final Answer would be: 9.4 inches

Hope this helps!
