Question

If the radius of a sphere is doubled, by how many times has its volume been increased

Answer 1

Answer:

8 times larger than the original

Step-by-step explanation:

In any three dimensional object,  cube sphere, cone, etc., if all of its dimensions increase by a factor of x then its volume increases by a factor of x³

In this case the dimensions double, so the volume increases by a factor of 2³ = 8
