Step-by-step explanation:
Let r and h be the radius and height of the cylinder respectively.
Given that, volume of the tank = 1.078 ×106 = 1078000 litre
= 1078 m3
= 1078 m3 (since 1l = 1/1000 m3)
diameter = 7m gives radius = 7/2 m
volume of the tank = πr2h cu. Units
1078 = 22/7 × 7/2 × 7/2 ×h
Therefore, height of the tank is 28 m
