As we know, capacity of cylindrical tank is essentially equal to its volume. Volume of a cylindrical tank = πr 2 h Where, r = radius of the tank and h= height of the tank ∵ 1 litre = 1000 cm 3 = 0.001 m 3 ∴ Capacity of cylindrical tank = 61.6 × 0.001 m 3 ⇒ πr 2 h = 61.6 × 0.001 ⇒ r = 0.07 m Now, diameter = 2r ∴ Diameter = 2 × 0.07 = 0.14 m = 14 cmRelated questions
