Answer 1

For a cylinder

`V_\textrm{cyl} = \pi r^2 h`

Since
`h = 2r`

`V_\textrm{cyl} = 2 \pi r^3`

We know that's 64 cubic meters,

`64 = 2 \pi r^3`

The sphere's volume is

`V = \frac 4 3 \pi r^3 = \frac 2 3 (2\pi r^3) = \frac 2 3 (64) = (128)/(3)`

Answer: 128/3 cubic meters

That may be that choice peeking out at the bottom; can't really tell
