<span>Area of circular metal=πr^2
=3.14 x 3.5 x 3.5 m^2
now,
total cost=area x rate
=3.14 x 3.5 x 3.5 x 3.25 $
=125.01 $</span>
        
                    
             
        
        
        
Answer:
2) y = x - 4
    y = -x + 2
    => x - 4 = -x + 2
    => 2x = -6
    => x = -3
    => y = -3 - 4 = -7
3) y = 3x + 1
    y = 5x - 3
    => 3x + 1 = 5x - 3
    => 2x = 4
    => x = 2
    => y = 3(2) + 1 = 7
4) 2x + y = 8 => y = -2x + 8
    y = x - 7
    => -2x + 8 = x - 7
    => 3x = 15
    => x = 5
    => y = 5 - 7 = -2
