Question

Shalini has to cut circles of diameter 1 1/4 from an aluminium strip of 8 3/4 by 1 1 /4 how many circles she can cut?

Answer 1

Diameter of Circle = $\frac{5}{4}$
Length of strip = $8 \frac{3}{4}= \frac{35}{4}$
Perimeter of circle = 2πr
                              =$\frac{5\pi}{4}= \frac{ 5\pi }{4}$
Number of circles she can cut =
$\frac{\frac{35}{4}}{\frac{ 5\pi }{4} } = \frac{35}{5\pi }= 2.2281692032865347007643726872152$

So She can cut only 2 circles
