Answer:
8 times
Step-by-step explanation:
We know that the radius of smaller sphere is r,
The volume of sphere is given by:
where V_1 is the volume of the small sphere.
As we know that the radius of large sphere is double of the smaller sphere, the radius of large sphere will be 2r
Let V_2 be the volume of large sphere
Separating 8 aside
We can see that the volume of large sphere is eight times the volume of small sphere ..
