Is anyone gonna help?!

shane_b · Answer

$$V_{cyl}=\pi r^2h$$If the radius is held the same, the h must go up by a factor of 8.

Sadly, the question doesn't say how the volume is being increased...by radius?   by height?

shane_b · Answer

Or even both...which means there could be multiple answers.

shane_b · Answer

I'd go with 8 assuming that only the height is being changed...and 8 is an available answer.
