Question

A milk tank is in the form of a cylinder whose radius is 1.5 m and height is 10.5 m. Find the quantity of milk in litres that can be stored in the tank.

Answer 1

$$\begin{gathered} r=1.5\mathrm{m} \\ h=10.5\mathrm{m} \\ \mathrm{Capacity}\mathrm{of}\mathrm{the}\mathrm{tank}=\mathrm{volume}\mathrm{of}\mathrm{the}\mathrm{tank}=\pi r^{2}h=\frac{22}{7}\times 1.5\times 1.5\times 10.5=74.25{\mathrm{m}}^3 \\ \mathrm{We}\mathrm{know}\mathrm{that}1{\mathrm{m}}^3=1000\mathrm{L} \\ \therefore 74.25{\mathrm{m}}^3=74250\mathrm{L} \end{gathered}$$
