If the height and diameter of the cylinder are doubled, by what factor will the volume of the cylinder change?
barxatty [35]

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.

Hope it helps and if it does, plz mark me brainliest
