The volume of a cylindrical water tank is 1 . 078 × 10 6 litres. If the diameter of the tank is 7 m , find its height.

Let r and h be the radius and height of the cylinder respectively. Given that, Volume of the tank = 1 . 078 × 10 6 litres = 1 . 078 × 1000000 = 1078000 litres Since, 1 l = 1 1000 m 3 = 1078 m 3 Diameter = 7 m gives radius = 7 2 m Volume of the tank = π r 2 h cu.units 1078 = 22 7 × 7 2 × 7 2 × h Therefore, height of the tank is 28 m .
