Question

A hemisphere bowl has inner diameter $\mathbf{11}\mathbf{.}\mathbf{2}\mathbf{}\mathbf{cm}$. Find the volume of milk it can hold.

Answer 1

Calculate the volume of the hemisphere bowl:

The radius of the hemisphere bowl $\left(r\right)=\frac{11.2}{2}=5.6\mathrm{cm}$

The volume$\left(V\right)$ of the hemisphere bowl can be computed as:

$$\begin{gathered} \therefore V=\frac{2}{3}\mathrm{\pi }{r}^3 \\ \Rightarrow V=\frac{2}{3}\times \frac{22}{7}\times {(5.6)}^3 \\ \Rightarrow V=\frac{2}{3}\times \frac{22}{7}\times 175.616 \\ \Rightarrow V=367.96{\mathrm{cm}}^3 \end{gathered}$$

Hence, the volume of the hemisphere bowl is $367.96{\mathrm{cm}}^3$.
