Question

The volume of a cylinder increased by 8 times the original volume. How many times greater are each of the dimensions of that new cylinder?

Answer 1

Is anyone gonna help?!

Answer 2

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

Answer 3

Alright

Answer 4

my choices are 2

3

4

8

Answer 5

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

Answer 6

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

Answer 7

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