# A rectangular she

Answer :

Given,

Dimension of rectangular sheet of paper = 30cm×18cm

Case (i)

When paper is rolled along its length ,

Then, 2πr = 30 = r = = h = 18 cm

So, volume of cylinder V1 = πr2h = Case (ii)

When paper is rolled along its width,

Then 2πr = 18 = r= = h = 30 cm

So, volume of cylinder thus form = Rato of volumes V1 : V2 = Rate this question :
