Answer to Problem 9WE
The ratio of amount of paint required for covering model to the actual airplane is
Explanation of Solution
Given information:
The scale factor according to model airplane kit package is
Calculation:
The ratio of the corresponding sides of any two similar geometric figures is termed as Scale factor.
Let the total area of the airplanes to cover the mode be
The theorem of similar solids states that if the scale factor of two similar solids is
Expression to determine the total area of two similar cones from the above theorem is:
Substitute
Therefore, the amount of paint required for covering model to the actual airplane is
