Question

two cylinders have identical bases with differnt lengths.the length of shorte cylinder is x where as the length of longer cylinder is 2x.which statement is true
1.the shorter cylinder has one half the surface area of the taller cylinder for all values of x.
2.the shorter cylinder has same surface area as the taller cylinder for some values of x.
3.The shorter cylinder has one half the volume of the larger cylinder for all values of x
4.The shorter cylinder has same volume as the larger cylinder for some values of x.

Answer 1

surface area = area of base and top (same for both) + height*2 pi r
so not the same and not twice

volume = area of base * height
ah ha, twice if you double height

Answer 2

which statement is true

Answer 3

I told you.

Answer 4

I dint understood .give me the number of the statement
Thanks a loooooooooooot
