Given:

Two different cylinders have the same volume.

To find:

The height of the cylinder 2

Solution:

Volume of the cylinder 1:


v = \pi {r}^(2) h


v = \pi * {3}^(2) * 24


v = 678.58401 \: {ft}^(3)


v = 678.58 \: {ft}^(3) (2 \: d.p)

Height of the cylinder 2:


h = \frac{v}{\pi {r}^(2) }


h = \frac{687.58}{\pi * {6}^(2) }


h= 5 .99996 \: ft


\huge\boxed{\sf{h=6 \: ft}}

Hence, the height of the cylinder 2 is 6 feet.
