Answer: I am pretty sure the answer is 40,320
Step-by-step explanation:
If you do 8x7x6x5x4x3x2 it equals 40,320
 
        
             
        
        
        
If you multiply length times width to get area, it's the same with division. You do area divided by length or width. The equation would be 225 divided by 13 3/4. 225/13 3/4= 16.36 inches. 16.36 > 16 inches, so the answer would be no. (The mirrors length and width are 13 3/4 inches by 16 9/25)
        
             
        
        
        
S = 2 π r h + 2 π r²  ( surface area of the cylinder )
2 π r h = S - 2 π r²
Answer:
h = ( S - 2 π r² ) / ( 2 π r )
