Area of the Base = 6 * side^2 / 4 * tan (180/6)Area of the Base = 6 * 16 / 4 * 0.57735Area of the Base = 96 / 2.3094 Area of the Base = 41.5692387633 
Area of 1 Face = 2 * 6 = 12Area of 6 Faces = 72
Total Area = 41.5692387633 + 72Total Area = 113.5692387633

We know that
<span>Figures can be proven similar if one, or more, similarity transformations (reflections, translations, rotations, dilations) can be found that map one figure onto another.
In this problem to prove circle 1 and circle 2 are similar, a translation and a scale factor (from a dilation) will be found to map one circle onto another.

</span>we have that
 <span>Circle 1 is centered at (4,3) and has a radius of 5 centimeters
</span><span> Circle 2 is centered at (6,-2) and has a radius of 15 centimeters
</span>
step 1
<span>Move the center of the circle 1 onto the center of the circle 2
</span>the transformation has the following rule
(x,y)--------> (x+2,y-5)
so
(4,3)------> (4+2,3-5)-----> (6,-2)
so
center circle 1 is now equal to center circle 2 
<span>The circles are now concentric (they have the same center)
</span>
step 2
A dilation is needed to increase the size of circle 1<span> to coincide with circle 2
</span>
scale factor=radius circle 2/radius circle 1-----> 15/5----> 3

radius circle 1 will be=5*scale factor-----> 5*3-----> 15 cm
radius circle 1 is now equal to radius circle 2 

A translation, followed by a dilation<span> will map one circle onto the other, thus proving that the circles are similar</span>
