Question

I need this answer pls. 100 points

Answer 1

135,590.4 lbs

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

Answer 2

• Radius=r=4ft
• Height=h=42ft

`\\ \sf\longmapsto V=\pi r^2h`

`\\ \sf\longmapsto V=(22)/(7)(4)^2(42)`

`\\ \sf\longmapsto V=22(16)(6)`

`\\ \sf\longmapsto V=22(96)`

`\\ \sf\longmapsto V=2112ft^3`

Now

Weight of milk

`\\ \sf\longmapsto 2112(64.2)=135,590lbs`
