Find volume and t.s.a?

Question

A RECTANGLE PAPER 11CM,4CM, IS TO FIND TO MAKE  A CYLINDER. FIND THE VOLUME AND T.S.A?

Answer 1

Nabeel,
 
The paper can be made into the cylinder in many orientations.  Either the 4cm or the 11cm can be used as the height of the cylinder.  As for the radius, how narrow and how wide determines the radius of the cylinder.  Because of this, you need to specify your orientations and radius.

 

Once you have those pieces of information down, you can find the total surface area using this formula.

 

 

T.S.A = 2πr² + 2πrh

 

 

where:

r = radius

h = height

π = pi

Answer 2

My mistake. You can make a cylinder, you cannot find the T.S.A. - total surface area - without two bases.
