Answer:
1.4
Step-by-step explanation:
Since we are dealing with a volume problem (3 dimensions) when you increase the radius by a factor of 2, you increase the volume by a factor of 2^3 or 8
So, the larger sphere has a volume 8 times greater than the smaller sphere.
Answer: 4/5
Step-by-step explanation: It is 8/10, but if you simplify it, it is 4/5.
