e = k.m
360 = k.60
k = 360/60 = 36/6 = 6
108 = 6.m
108/6 = m = 18
What the question?
Or picture
Data: (Cylinder)
h (height) = 8 cm
r (radius) = 5 cm
Adopting:

V (volume) = ?
Solving:(<span>Cylinder volume)
</span>




<span>Note: Now, let's find the volume of a hemisphere.
</span>
Data: (hemisphere volume)
V (volume) = ?
r (radius) = 5 cm
Adopting:

If: We know that the volume of a sphere is

, but we have a hemisphere, so the formula will be half the volume of the hemisphere

Formula: (<span>Volume of the hemisphere)
</span>

Solving:





<span>Now, to find the total volume of the figure, add the values: (cylinder volume + hemisphere volume)
</span>
Volume of the figure = cylinder volume + hemisphere volume
Volume of the figure = 628 cm³ + 261.6 cm³
The area of the wings of the model is 100000 square centimeters
<h3>How to determine the model area of the wings?</h3>
The given parameters are:
Scale factor, k = 1/2
Actual area of wings, A = 40 square meters
The model area is calculated as
Model area = Actual area * k^2
This gives
Model area = 40 * (1/2)^2
Evaluate
Model area = 10 square meters
Convert square meters to square centimeters
Model area = 10 * 10000 square centimeters
Evaluate
Model area = 100000 square centimeters
Hence, the area of the wings of the model is 100000 square centimeters
