We need to find the volume of the given cylinder.

The volume V of a cylinder with radius r and height h is given by:


V=\pi r²h

In this problem, we need to use 3 for π, and we have:


\begin{gathered} r=\frac{4\text{ cm}}{2}=2\text{ cm} \\ \\ h=10\text{ cm} \end{gathered}

Thus, we obtain:


\begin{gathered} V=3\cdot(2\text{ cm})^2\cdot10\text{ cm} \\ \\ V=3\cdot4\text{ cm}^2\cdot10\text{ cm} \\ \\ V=3\cdot4\cdot10\text{ cm}^2\text{cm}^ \\ \\ V=120\text{ cm}^3 \end{gathered}

Answer

V = 120 cm³
