To determine the volume of a cylinder:


V=\pi r^2h

A cube is said to have equal base where, the volume = 64cm^3


\begin{gathered} V=a^3 \\ 64=a^3 \\ 4^3=a^3 \\ a=4\operatorname{cm} \end{gathered}

The circular base of the cylinder is equivalent to the half the length of the cube


\text{circular bse = }(a)/(2)=(4)/(2)=2\operatorname{cm}
\begin{gathered} \text{Volume of the cylinder = V = }\pi r^2h \\ V=(22)/(7)x2^2x\text{ 2} \\ V=(176)/(7)=25(1)/(7)cm^3 \end{gathered}

Hence the correct answer = 25 1/7 cm^3=
