Answer:
1,499 liter
Step-by-step explanation:
The rest of the question is:
each is in the shape of a cylinder of radius 21 cm and height is 50 cm.
==============================================================
The quantity of water left in the tanker after distribution
= Total quantity - Distributed quantity
Total quantity = Volume of the giving figure
= Volume of the cylinder + volume of 2 hemispheres
Volume of the cylinder of 4.2 m length and 1.2 m of a diameter.
L = 4.2 and radius = r = 0.5 * diameter = 0.5 * 1.2 = 0.6
Volume of cylinder = π r² L = (22/7) * 0.6² * 4.2 = 4.752 m³
Volume of 2 hemispheres = 2*0.5 * (4/3) π r³ = (4/3) * (22/7) * 0.6³
=792/875 m³
Total volume = 4.752 + 792/875 = 198/35 ≈ 5.657 m³
Distributed quantity = 60 times the volume of a cylinder of radius 21 cm and height is 50 cm
Distributed quantity = 60 * π r² L = 60 * (22/7) * 21² * 50 = 4,158,000 cm³
Since 1 m³= 1,000,000 cm³
Distributed quantity = 4,158,000 cm³ = 4.158 m³
The quantity of water left in the tanker after distribution =
= 198/35 - 4.158 ≈ 1.499 m³
Since 1 m³= 1,000 liter
The quantity of water left in the tanker after distribution =
= 1.499 m³ = 1.499 * 1000 = 1,499 liter
