Answer:
Step-by-step explanation:
There are 3 boxes. The formula for volume is lxhxw, (length x height x width)
The answer is 0.154 m
Step 1. Calculate the volume of gasoline tank (V) using the known mass (m) and density of gasoline (D).
D = m/V
⇒ V = m/D
D = 719.7 kg/m³
m = 45.0 kg
V = 45.0 kg/719.7 kg/m³ = 0.0625 m³
Step 2. Calculate the depth of the tank (d) using the known volume (V) of gasoline and width (w) and length (l) of the tank:
V = d * w * l
0.0625 = d * 0.900 * 0.450
0.0625 = d * 0.405
d = 0.0625 / 0.405
d = 0.154 m
We asked to solve the volume of the cone and we know that the formula for solving the volume is shown below:
V = 1/3*pi*r²*h where "r" for the radius and "h" for the height
We have the given values such as:
r= diameter/2 = 12/2
r= 6 inches
h=6 inches
Solving for the volume:
V= 1/3 *pi*6²*6
V=72pi in³
The answer is the letter "A" 72pi inches³.
