Answer:
704π m^2
Step-by-step explanation:
Given data
radius r= 16m
Slant height l= 28m
Required
The surface area of the cone
The expression for the surface area is given as
T.S.A=πrl+πr^2  
substitute
T.S.A=π*16*28+π*16^2
T.S.A=448π+256π
T.S.A=704π m^2
Hence the T.S.A is 704π m^2

Answer:
43
Step-by-step explanation:
90-47=43
 
        
             
        
        
        
17/80 = p/100
p = 17/80 * 100
p = 0.2125 * 100
p = 21.25
        
             
        
        
        
The answer is 240 :3
60+60= 120
120+60 = 180 
and 60 more would be 240 
60 fours would be 240
3  60's  would be 180.  So your answer is 240
