Question

An overhead water tanker is in shape of cylinder has capacity of 616 litres. the diameter of tank is 5.6 M find the height of the tank

Answer 1

Given Diameter = 5.6 m

=> Radius = 5.6/2

=> Radius = 2.8 m

Taking capacity as its volume,

1 litre = 0.001 m³
616 litres = 0.616 m³

we know that,

volume = πr²h

=> 0.616 = π × (2.8)² × h

=> 0.616 = 22/7 × 7.84 × h

=> 0.616 = 22 × 1.12 × h

=> 24.64 × h = 0.616

=> h = 0.616/24.64

=> h = 0.025 metre.

or, h = 2.5 cm

Hope it helps dear friend ☺️✌️

Answer 2

Answer:

Height(h) = 2.5 cm (or) 0.025 cm

Step-by-step explanation:

(i)

Given, volume of tanker = 616 litres

                                        = 616000 cm³.

(ii)

Given, diameter of tank = 5.6 m

                                       = 560 cm.

Then, radius of the tank = 560/2 = 280 cm.

Now,

We know that volume of cylindrical tanker = πr²h

⇒ 616000 = (22/7) * (280)² * h

⇒ 616000 * 7 = 22 * (280)² * h

⇒ 4312000 = 1724800 * h

⇒ h = 2.5 cm (or) 0.025 m.

Hope it helps!
