    1. Best Answer

      Radius of circle = 2 cm and side of aluminium square sheet = 6 cm
      According to question,
      Area of aluminium sheet left = Total area of aluminium sheet – Area of circle
      = side x side -πr²
      = 6 x 6 – 22/7x 2 x 2
      = 36 – 12.56
      = 23.44 cm²
      Therefore, the area of aluminium sheet left is 23.44 cm².
