Answer:
Step-by-step explanation:
Expand:
Simplify:
Subtract 7 from both sides:
Subtract 5x from both sides:
Divide both sides by 20:
18x-2+12x+2=180
30x=180
x=180:30
x=6
<vxy=12*6+2=72+2=74
The volume of the cone is 84.9 km³
<h3>How to find the volume of a cone?</h3>
Volume of a cone = 1 / 3 πr²h
where
Therefore,
radius = 3 km
height = √9.5² - 3²
height = √81.25
height = 9.01387818866
height = 9.014 km
Volume of a cone = 1 / 3 × 3.14 × 3² × 9.014
volume of the cone = 254.732197612 / 3
volume of the cone = 84.9107325372
volume of the cone = 84.9 km³

5 is in the units place, so it means 5.
8 is in the tenths place, so it means 0.8.
3 is in the hundredths place, so it means 0.03.
5.83 = 5 + 0.8 + 0.03
