Question

a rectangular sheet of paper,44cm long and 16cm broad, is rolled along its lenght to form a cylinder

Answer 1

When length of a rectangle is rolled to form a cylinder then length is equal to circumference of circle.

Means 44cm = 2* pi*r

=) 2* 22/7 * r = 44cm

=) r = 7cm.

And height is equal to width = 16cm.

Hence r= 7cm and h= 16cm.

Find anything which u will want to find : CSA or TSA or Volume.

Hope it's helpful to u.

Answer 2

Here when you form a rectangle to a cylinder 
The length of the rectangle =  Height of the Cylinder
Breadth = Circumference of the circle = 2*pie*r
You can find anything what ever you want
