Answer:
8
Step-by-step explanation:
First off, we need to recognize that the formula for the volume of a sphere is .
Then, we can plug in our r values one at a time.
The volume for the sphere with a 6-inch radius is about 904.779.
The volume for the sphere with a 3-inch radius is about 113.097.
To find how much greater the larger sphere is, we simply create a ratio between the two numbers:
Do the division to find that the volume of the larger sphere is about 8 times the volume of the smaller sphere.
