Answer:
Given:-
Diameter of circle = 5/4cm
Dimensions of aluminium strip = 35/4 by 5/4
Solution:-
[tex]Nilabh \: will \: able \: to \: cut \: \frac{ \frac{35}{4} }{ \frac{5}{4} } = 7 \: circles[/tex]
Therefore,
Nilabh will able to cut 7 circles from the strip, so we will subtract; Area of 7 circles from the total area of aluminium strip to obtain the remaining aluminium.
So, Total aluminium wasted = Area of aluminium strip - Area of 7 circles.
[tex] \frac{35}{4} \times \frac{5}{4} - 7 \times \pi \times ( \frac{5}{8} )^{2} [/tex]
[tex]»» \: 10.9 - 8.59[/tex]
[tex]»» \: 2.35cm[/tex]
Hence,Nilabh will cut 7 full circles and 2.35 cm is the wastage of aluminium strip.
