A circular pool with a diameter of 18 ft will have a uniform
4 ft concrete walkway poured around it. If the concrete cost $4.25 a square
foot, how much will it cost for the concrete?
This can be solve be solving the area of walkway
Area of walkway is equal to = (pi)( 9 ft +4) ^2– (pi)(9ft)^2
= 276.46 sq ft
Cost = 276.46 sq ft * ($4.25 a square foot) = $1174.70
 
        
                    
             
        
        
        
64 and 64 for the simplify the following
8.5 for evaluate the expression
$5.50 + $1.99n is for the movies question
x divided by 2 minus 18 is for the football fans
hope this helped some...
