. A right cylindrical drum is to hold 7.35 cubic feet of liquid. Find the dimensions (radius of the base and height) of the drum which would minimize the surface area. What is the minimum surface area

Step-by-step explanation:

r = Radius

h = Height

Volume of cylinder =

Surface area is given by

Differentiating with respect to radius we get

Equating with zero we get

So, the value of the function is minimum at

So, the radius and height which would minimize the surface area is 1.05 feet and 2.12 feet respectively.

Surface area

The minimum surface area is .
