Answer :

Let the radius and height of right circular cylinder be r and h respectively.

Given: Volume of Cylindrical can = 100 cm^{3}

Volume of a cylinder = πr^{2}h

πr^{2}h = 100

… 1

Surface of a cylinder, S = 2πrh + 2πr^{2}

From equation we get,

Condition for maxima and minima

So, for

>0

This is the condition for minima

From equation 1,

Hence, required dimensions of cylinders are radius = and height =
