The side lengths of two different cubes are 35 cm and 42 cm. what is the ratio of the volume of the smaller to the volumes of the larger?

First we look for the result of the volume for both:
 the smaller:
 V1 = (35) ^ 3
 V1 = 42875 cm ^ 3
 the larger
 V1 = (42) ^ 3
 V1 = 74088 cm ^ 3
 Then, we have to:
 V1 / V2 = (42875) / (74088)
 V1 / V2 = 0.578703704
  
 The ratio of the volume of the smaller to the volumes of the larger is:
 V1 / V2 = 0.578703704

Step-by-step explanation:

Circumference=2πr=2(3.14)(4)=25.12 in.
