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

$V = \frac 4 3 \pi r^3 = \frac 2 3 (2\pi r^3) = \frac 2 3 (64) = \dfrac{128}{3}$

Answer: 128/3 cubic meters

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