The scale factor from the model of a human ear to the actual ear is 55:2. If one of the bones of the model is 8.25 centimeters long, how long is the actual bond of the human ear?

Given :

Ratio of model of a human ear to the actual ear = 55:2

bones of the model = 8.25

Modal of human ear/actual ear  = 55/2

actual ear = 2/55 * modal of human ear

actual ear = 2/55 * 8.25

actual ear = 0.3

 

Thus, actual bone of human ear is 0.3
