-3.7 + w = 9.24
Solving
-3.7 + w = 9.24
Solving for variable 'w'.
Move all terms containing w to the left, all other terms to the right.
Add '3.7' to each side of the equation.
-3.7 + 3.7 + w = 9.24 + 3.7
Combine like terms: -3.7 + 3.7 = 0.0
0.0 + w = 9.24 + 3.7
w = 9.24 + 3.7
Combine like terms: 9.24 + 3.7 = 12.94
w = 12.94
Simplifying
w = 12.94</span>

Answer:
- hemisphere volume: 262 m³
- cylinder volume: 942 m³
- composite figure volume: 1204 m³
Step-by-step explanation:
A. The formula for the volume of a hemisphere is ...
V = (2/3)πr³
For a radius of 5 m, the volume is ...
V = (2/3)π(5 m)³ = 250π/3 m³ ≈ 261.799 m³
__
B. The formula for the volume of a cylinder is ...
V = πr²h
For a radius of 5 m and a height of 12 m, the volume is ...
V = π(5 m)²(12 m) = 300π m³ ≈ 942.478 m³
__
C. Then the total volume is ...
V = hemisphere volume + cylinder volume
V = 261.799 m³ +942.478 m³ = 1204.277 m³
__
Rounded to the nearest integer, the volumes are ...
- hemisphere volume: 262 m³
- cylinder volume: 942 m³
- composite figure volume: 1204 m³

As a rule, you only want to round the final answers. Here, the numbers are such that rounding the intermediate values still gives the correct final answer. That is not always the case.
The first rectangle has a length of 20cm and a width of 2cm for the area to be 40cm. so, the dimensions must be multiplied by 4 to equal 160cm.
