Please show step by step of working out the value of r for which is A minimum and calculate the minimum surface area of the container. The total surface area, Acm^2, of each container is modelled by function A= πr^2+100/r.

(remember to use the derivative to show you have found the minimum)

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

answer: you need the equation in the question so i can answer it

answer: yard ramps with a level off platform are typically 36 feet long. truck, rather than at an angle, enabling access to those pallets at the very back of the truck. if you are using your yard ramp to convert a loading dock into a drive-in door, we even at 60 inches (5 feet) high and a 30 foot ramp, the slope of the ramp will be less
