Question 610237
How tall is the actual fuel tank in meters?
Model: 12cm
12cm*(1.25m/1cm)=15m
Actual:15m
---------------------------------------------------------
What is the scale factor between model and fuel tank?
Model: 1cm
Actual: 1.25m or 125 cm
Ration: model/actual -> 1/125
---------------------------------------------------------
Determine the volume in cubic meters.
Find Radius of Actual:
Model: 5cm
5cm*(1.25m/1cm)=6.25m
Actual:6.25m
---------------------------------------------------------
Volume of Cylinder:V=πr^2*h (r=radius)(h=height)(V=Volume)
V=π6.25^2*15
V=π39.0625*15
V=585.9375π or Approx. 1,839.84 cubic meters
---------------------------------------------------------
Surface Area of a Cylinder: Sa=2πr^2+2πr*h (r=radius)(h=height)(Sa=Surface Area)
Sa=2π6.25^2+2π6.25*15
Sa=2π39.0625+2π93.75
Sa=78.125π+187.5π
Sa=265.625π or 834.0625 Square meters
