Question

A tank of cylindrical shape has a radius of $2.8m$ and its height of $3.5m$. Complete the activity to find how many litres of water the tank will contain.

Answer 1

Finding the capacity of the tank:

Given ,

Radius of tank $\left(r\right)$ $=2.8m$

Height of tank$\left(h\right)$ $=3.5m$

The amount of water that water tank will contain $=$ volume of the cylinder

$$\begin{gathered} ={\mathrm{\pi r}}^2\mathrm{h} \\ =\frac{22}{7}\mathrm{x}2.8\mathrm{x}2.8\mathrm{x}3.5 \\ =86.24{\mathrm{m}}^3 \\ =86.24\mathrm{x}1000[1{\mathrm{m}}^3=1000\mathrm{litres}] \\ =86240\mathrm{litres} \end{gathered}$$

Hence, the amount of water that water tank will contain $=86240\mathrm{litres}$.
