Let $\displaystyle r$ be the radius of the sphere. Then the radius of the base of the cylinder is also $\displaystyle r$, and the height of the cylinder is $\displaystyle h = 2r$.

The volume of the cylinder is

$\displaystyle V_{1} = \pi r^{2} h$,

which, after substituting, is

$\displaystyle V _{1} = \pi r^{2} (2r)$

$\displaystyle V_{1} =2 \cdot \pi r^{2}\cdot r$

$\displaystyle V_{1} =2 \pi r^{3}$

The volume of the sphere is 

$\displaystyle V_{2} = \frac{4}{3} \pi r^{3}$

Therefore, the ratio of the former to the latter is

$\displaystyle \frac{V_{1} }{V_{2}}=\frac{ 2 \pi r^{3}}{\frac{4}{3}\pi r^{3}}$

$\displaystyle \frac{V_{1} }{V_{2}}=\frac{ 2 }{\frac{4}{3} } = 2 \cdot \frac{3}{4} = \frac{3}{2}$

and 

$\displaystyle V_{1} = \frac{3}{2}V_{2}$

That is, the volume of the cylinder is $\displaystyle \frac{3}{2}$ times that of the sphere, so the volume of the cylinder is

$\displaystyle V_{1} = \frac{3}{2} \cdot 100 = 150$.
