3.20 × 105 gallons of tar (SG = 1.20) is stored in a 20.0-ft tall storage tank. What is the total mass of the liquid in the tank

lilavasa [31]

Answer:

Mass of the liquid in the tank will be $1.45\times 10^8kg$

Step-by-step explanation:

We have given volume of tar $V=3.20\times 10^5gallon$

1 gallon = 3.785 liter

So $3.20\times 10^5gallon=3.20\times 10^{5}\times 3.785=12.112\times 10^5liter$

Specific gravity = 1.2

Density of water $=1000kg/m^3$

We know that specific gravity $=\frac{density\ of\ liquid}{density\ of\ water}$

$1.2=\frac{density\ of\ liquid}{density\ of\ water}$

Density of liquid $=1200kg/m^3$

So mass of liquid = volume × density

= $12.112\times 10^5\times 1200=1.45\times 10^8kg$

So mass of the liquid in the tank will be $1.45\times 10^8kg$

Please help meee!!! 5 stars to the best answer.

vovikov84 [41]

Answer:

3 cm

Step-by-step explanation:

First, find the volume of the cone.

V = $\frac{1}{3}$ $\pi$ r²h

V = $\frac{1}{3}$ (3.14)(9)(12)

V = 113.04

This means the sphere is also 113.04

Use the formula V = $\frac{4}{3}$ $\pi$ r³

113.04 = $\frac{4}{3}$ (3.14)r³

113.04 = 4.19r³

26.98 = r³

3 ≈ r
