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

Capacity of water tank = Volume of the cylindrical tank
$$=\pi r^{2} h \\ =22 / 7 \times 2.8 \times 2.8 \times {3.5} \\ ={86.24} \mathrm{~m}^{3} \\ ={86.24} \times 1000 \text { litre } \\ ={86240} \text { litre }$$
