Question

Avi's pet hamster Chubby loves to run in his hamster wheel. During one "race", Avi counts 100 rotations of the wheel. She wants to know how far Chubby ran, so she measures the diameter of the wheel and finds that it is 20 cm. How far did Chubby run? Round your answer to the nearest cm

Answer 1

Answer:

Chubby ran a distance of 6,283 m

Step-by-step explanation:

The length of one run is simply equal to the circumference of the circle

Mathematically, C = pi * d

C = 22/7 * 20 = 62.83 cm

So if one rotation is a distance of 62.83 cm, then 100 rotations will be a distance of;

62.83 * 100 = 6,283 m
