The length of a rectangle is 10 feet longer than it is wide. If each side is increased 10 feet, then the area is multiplied by 2

harina [27]

Answer:

The with and length of the original rectangle are:

width: 20 ft

Length: 30 ft

Step-by-step explanation:

Lets check

Yes, 30 is 10 longer then 20,

the area of the original is 600

if it was 40 and 30 then it would equal 1200

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 cont

Genrish500 [490]

Answer:

A = 59.63cm^2

Step-by-step explanation:

You have the following function for the surface area of the container:

$A=\pi r^2+\frac{100}{r}$ (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.

$\frac{dA}{dr}=\frac{d}{dr}[\pi r^2+\frac{100}{r}]\\\\\frac{dA}{dr}=2\pi r-\frac{100}{r^2}$ (2)

Next, you equal the expression (2) to zero and solve for r:

$2\pi r-\frac{100}{r^2}=0\\\\2\pi r=\frac{100}{r^2}\\\\r^3=\frac{50}{\pi}\\\\r=(\frac{50}{\pi})^{1/3}$

Finally, you replace the previous result in the equation (1):

$A=\pi (\frac{50}{\pi})^{2/3}+\frac{100}{(\frac{50}{\pi})^{1/3}}}$

$A=59.63$

The minimum total surface area is 59.63cm^2
