A circular paper is folded along its diameter, then again it is folded...
If we unfold the circle we will observe that total 9 small circles of radius are cut off
thus total which is taken out from circle is
= πr^2(9)
=3.14*1*9
=28.26cm2
area of circle(orignal i.e bigger one) =
πr^2=3.14*5*5
=78.5
area of remaining part=area of circle-area of taken out part
=78.5-28.26
=50.24
ratio=78.5:50.24
=25:16
