The volume of a cylinder is given by:


V=\pi\cdot r^2\cdot h

Where:

V = Volume = 141 cm³

h = Height

r = radius = 3cm

π = 3.14

Therefore:


\begin{gathered} 141=3.14\cdot(3^2)\cdot h \\ 141=28.26h \end{gathered}

Solve for h:


\begin{gathered} h=(141)/(28.26) \\ 5.0\operatorname{cm} \end{gathered}
