The ratio between the surfaces areas of the two prisms is equal to 6.25.
<h3>How to get the ratio of the surface areas?</h3>
The ratio between the volumes of the prisms is:
This number is equal to the cube of the scale of dilation applied to the dimensions of the smaller prism, so the scale factor is:
And the ratio between the areas should be the square of the scale factor, then we will have that the ratio between the surface areas of the two prisms is:

Step-by-step explanation:
A tank has the format of a cylinder.
The volume of the cylinder is given by:
In which r is the radius and h is the heigth.
The problem states that the diameter is measured to be 15.00 ft. The radius is half the diameter. So, for this tank
ft
The height of the tank is 22 ft, so .
a) Volume of the tank in :
b) Volume of the tank in :
We must convert both the radius and the height to m.
Each feet has 0.30 m, so:
Radius:
1 feet - 0.30m
7.5 feet - r m
Height
1 feet - 0.30m
22f - h m
The volume is:
c) Volume of the tank in :
Each m has 100 cm.
So
The volume is:
