An overhead water tanker is in the shape of a cylinder has capacity of 616 litres. The diameter of the tank is 5.6 m. Find the height of the tank.

Given, An overhead water tanker is in the shape of a cylinder has capacity of 616 litres i.e. the volume of the cylinder = 616m3.

Diameter of the cylinder = 5.6m


Radius of the cylinder = = 2.8m


Volume of the cylinder = πr2h.


616 = 3.14 × 2.82 × h


h =


h = 25m
