Answer 1

Answer:                                                                                                                       Wastage of aluminium strip is 0.57cm^2.    

Step-by-step explanation:

Area of aluminium strip: 8 3/4 x 1 1/4 = 35/4 x 5/4 = 175/16 cm^2.                               Area of circle of diameter 1 1/4 = 5/4 = 5/4 x 1/2 pie r^2 = 22/7 x 5/8 = 110/56.      No. of circles that cut out is 175/16 divided by 110/56 = 5.                                                    Wastage of aluminium strip is 0.57cm^2.                                                                        Number of circles cut is 5.
