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

A visible streak of light which shows the path of rocky object which has entered Earth’s atmosphere is?

Alika [10]

The answer is a meteor.
Meteors make flashing light when they enter the Earth's atmosphere. This is actually meteors on fire, because our atmosphere makes them burn when they come in contact, and crashes them under the pressure. This makes up for a beautiful sight on the night sky, and people often refer to the burning meteors as ''falling stars'', and make wishes as well.

When evaluating an argument, one should always take into consideration the existence and merit of any unstated premises. t or f

wolverine [178]

Answer:

True.

Explanation:

An argumentative writing can be defined as an expression of a writer's position (stance) on a subject matter or topic.

A claim can be defined as a statement that is used by a writer to prove, substantiate or support an argument.

Thus, a claim is an assertive statement expressed by a writer to prove that an argument is true or real.

This ultimately implies that, when writers engage in an argument or write an argumentative essay, they make use of a claim to state or express their opinions about the subject matter or topic.

All arguments generally have an unstated premise and as such when evaluating an argument, one should always take into consideration the existence and merit of any unstated premises. Premises connotes claims that fundamentally serves as a reason in an argument.
