Answer:
A = 59.63cm^2
Step-by-step explanation:
You have the following function for the surface area of the container:
(1)
where r is the radius of the cross sectional area of the container.
In order to find the minimum surface are you first calculate the derivative of A respect to r, to find the value of r that makes the surface area a minimum.
(2)
Next, you equal the expression (2) to zero and solve for r:
Finally, you replace the previous result in the equation (1):
The minimum total surface area is 59.63cm^2
