Surface Area of a can is 517.8 cm^2. Maximize the volume of this can using the measured surface area.

mafiozo [28]

Answer:

$r = 5.24$ --- Radius

$h = 10.48$ --- Height

Explanation:

Given

Object: Can (Cylinder)

$Surface\ Area = 517.8cm^2$

Required

Maximize the volume

The surface area is:

$S.A = 2\pi r^2 + 2\pi rh$

Substitute 517.8 for S.A

$517.8 = 2\pi r^2 + 2\pi rh$

Divide through by 2

$258.9 = \pi r^2 + \pi rh$

Factorize:

$258.9 = \pi r(r + h)$

Divide through by $\pi r$

$\frac{258.9}{\pi r} = r + h$

Make h the subject

$h = \frac{258.9}{\pi r} - r$ --- (1)

Volume (V) is calculated as:

$V = \pi r^2h$

Substitute (1) for h

$V = \pi r^2(\frac{258.9}{\pi r} - r)$

Open Bracket

$V = 258.9r - \pi r^3$

Differentiate V

$V' = 258.9 - 3\pi r^2$

Set V' to 0

$0 = 258.9 - 3\pi r^2$

Collect Like Terms

$3\pi r^2 = 258.9$

Divide through by 3

$\pi r^2 = 86.3$

Divide through by $\pi$

$r^2 = \frac{86.3}{\pi}$

$r^2 = \frac{86.3*7}{22}$

$r^2 = \frac{604.1}{22}$

Take square root of both sides

$r = \sqrt{\frac{604.1}{22}$

$r = 5.24$

Recall that:

$h = \frac{258.9}{\pi r} - r$

Substitute 5.24 for r

$h = \frac{258.9}{\pi * 5.24} - 5.24$

$h = \frac{258.9*7}{22 * 5.24} - 5.24$

$h = \frac{1812.3}{115.28} - 5.24$

$h = 15.72 - 5.24$

$h = 10.48$

Hence, the dimension that maximize the volume is:

$r = 5.24$ --- Radius

$h = 10.48$ --- Height

In an essay, you will choose an entrepreneur and argue whether the free enterprise system was necessary for that individual to m

wariber [46]

Answer:

Free enterprise systems, refers to an economy where

the market determines prices, products, and services

rather than the government. In other words, businesses

and services are free of government control. As the

statement mentions it allows the supply and demand of

consumers to determine the success or failure of a

business. We can grab for example Steve Jobs, one

of the creators of the multi-billion company called

Apple. An economy where enterprises are forced to

follow the government rules, tend to limit

themselves to provide just the necessary. On the other

hand, if a business goes to the free market it opens

a whole new world of possibilities. When apple first

appeared in the market it wasn't very popular, but

then started growing popularity with its products

and slogans. Apple needed to become a free enterprise

business for it to become what it is now. Without

rules or restrictions, businesses could grow much more;

but always taking to detail that the supply and demand

will be the changing factor of success or failure.
