Answer 1

@johnweldon1993 can you help with this too? :D

Answer 2

Trying to kill me XD

Okay so same set up here

We set up a proportion of height to radius

\[\large \frac{H_{bigger}}{R_{Bigger}} = \frac{H_{smaller}}{R_{smaller}}\]
\[\large \frac{11.6ft}{5.8ft} = \frac{x}{2.9ft}\]

Solve for 'x'

\[\large x = \frac{11.6ft \times 2.9ft}{5.8ft} = 5.8ft\]

So now that we have the height of the smaller one, we can solve for the volume

\[\large V = \pi r^2 h\]
or for you

\[\large V = \pi (2.9ft)^2 \times 5.8ft = ?\]

Answer 3

I got 153.12 :o @johnweldon1993 ??
