Answer:
8
Step-by-step explanation:
Let the initial values of the height and the diameter be h and 2r.
Then the volume of the non-enlarged cylinder is \pi r^2 h
The volume of the enlarged cylinder becomes \pi(2r)^2 2h = \pi 4r^2*2h =8*\pi r^2 h.
So the 2nd volume is obtained by multiplying the 1st volume by 8.
Therefore the cylinder is enlarged by factor 8.
