As performed in the real lab:

Materials Required:

Colored papers, a pair of scissors, gum.

Procedure:

• Cut a rectangular sheet of paper of length l = given circumference of base of cylinder, breadth b = given height. [Fig (a)].
• Gently curve the paper so that the two (shorter) sides come together.
• Join the edges together by cello tape.[Fig (b)].

               Fig (a)                                                                  Fig (b)

As performed in the simulator:

• Create rectangle by providing length and breadth.
• Click on button "Draw Rectangle" to draw rectangle.
• Click on the rectangular sheet to fold and create a right circular cylinder .

Observation:

• The rectangle transforms into a cylinder.
• The height of the cylinder is b.
• The circumference of the base circle is l.
