A cylindrical jar without a lid has to be constructed using a given surface area of a metal sheet. If the capacity of the jar is to be maximum, then the diameter of the jar must be k times the height of the jar. The value of k is -
1
2
3
4
For any open cylinder of surface area, when it has maximum volume, the height and radius of the base are equal.
Therefore diameter of cylinder = Twice of its height
So, k will be equal to 2.
