Question

The radius of a sphere is half the radius of another sphere what is the ratio of their respective volumes

Answer 1

Answer:

8:1

Step-by-step explanation:

radius of first sphere is x

radius of second sphere is x/2

volume of sphere is 4/3πr^3

4/3πr^3=4/3πr^3

4/3πx^3=4/3πx^3/2

x^3=x^3/2

1=1/8

8:1 is the answer
