If the scale factor of two similar solids is a:b, then the ratio of their areas is a^2: b^2
In this case the scale factor of these are 3:4. Therefore the ratio of areas are 3^2: 4^2
Therefore, if the scale factor of two similar cylinders is 3:4, then the ratio of their areas is 9:16
Can you create a general formula for that approach?
the general formula is dependant on the formula of the shape your dealing with
A=2πr 2 +2πrh
Sub each scale factor ratio into the equation (ie r -> (3r), h->(3h)), set as a ratio and reduce where you can. cylinder worked out nice. Is that kinda what you were after>
