Question

The diameter and height of a cylindrical tank is 1.75 m and 3.2 m respectively. How much is the capacity of tank in litre? (π = $\frac{22}{7}$)

Answer 1

Diameter = 1.75 m
Radius = 0.875 m
Height = 3.2 m
Capacity = $\mathrm{\pi }{r}^{2}h=\frac{22}{7}\times {\left(0.875\right)}^2\times 3.2=7.7$ m³
$$\begin{gathered} 1{\mathrm{m}}^3=1000\mathrm{L} \\ 7.7{\mathrm{m}}^3=7.7\times 1000=7700\mathrm{L} \end{gathered}$$
