Answer:
709.93 kg/m³
Explanation:
Density: This can be defined as the ratio of the mass of a body to the volume of that body. The S.I unit of density is kg/m³
From the question above,
D = m/v.............................. Equation 1
Where D = density, m = mass, v = volume.
Note: The volume of the liquid is equal to the volume of the height occupied by the liquid in the container
Since the tank is cylindrical,
v = πr²h........................ Equation 2
Where r = radius of the the tank, h = height of the liquid in the tank
Substitute equation 2 into equation 1
D = m/(πr²h)............... Equation 3
Given: m = 14014 kg, r = 1.35 m, h = 3.45 m, π = 3.14
Substitute into equation 3
D = 14014/(3.14×1.35²×3.45)
D = 14014/19.74
D = 709.93 kg/m³
