Answer:
531.167 ft²
Step-by-step explanation:
Given data
Dimension of pool
Diameter =24ft
Radius =12ft
If the cover must hang by 1ft around, then the diameter is 26ft
Radius =13ft
Area of cover = πr²
Substitute 
Area = 3.142*13²
Area =3.143*169
Area =531.167 ft²
Hence the minimum area is 531.167 ft²
 
        
             
        
        
        
Its 144. you just subtract the 121 from 265.
        
             
        
        
        
Well, 

  So he rode 

 miles, or if they want it as a fraction, it would be 
 
 
        
        
        
2/9=0.222
 The answer would be 0.
        
                    
             
        
        
        
It has landed on its side 25/30 times, on the top 4/30 times 25/30=5/6,1/30=0.2/6 and 4/30=0.8/6.
