Sphere A is similar to Sphere B.
All spheres are similar.
-----------------
The Radius of sphere A is 3 inches, and the radius of a sphere B is 6 inches. How many times larger is the volume of Sphere B compared to Sphere A
--------
Vol+=+4pi%2Ar%5E3%2F3+=+kr%5E3 (k is a constant)
r*2 --> Vol*8
---
8 times the volume = 7 times larger
Not 8 times larger. 8 times as large = 7 times larger.
