Answer:

135,590.4 lbs

Step-by-step explanation:

the radius of tank = r = 4 ft

the length of tank = h = 42 ft

the volume of tank truck = π. r².h

= 22/7 × 4² x 42

= 132×16

= 2,112 ft³ (= the volume of milk)

so, the weight of milk =

2,112 × 64.2 = 135,590.4 lbs
  • Radius=r=4ft
  • Height=h=42ft

[tex]\\ \sf\longmapsto V=\pi r^2h[/tex]

[tex]\\ \sf\longmapsto V=\dfrac{22}{7}(4)^2(42)[/tex]

[tex]\\ \sf\longmapsto V=22(16)(6)[/tex]

[tex]\\ \sf\longmapsto V=22(96)[/tex]

[tex]\\ \sf\longmapsto V=2112ft^3[/tex]

Now

Weight of milk

[tex]\\ \sf\longmapsto 2112(64.2)=135,590lbs[/tex]
