A hemisphere of radius 8 sits on a horizontal plane. A cylinder stands with its axis vertical, the center of its base at the center of the sphere, and its top circular rim touching the hemisphere. Find the radius and height of the cylinder of maximum volume.

Answers

Answer 1

The dimensions of the cylinder that has the maximum volume can be

found be finding the maximum value of the volume function.

[tex]\mathrm{The \ \underline{height \ of \ the \ cylinder \ of \ maximum \ volume \ is \ \dfrac{8}{\sqrt{3} }}}[/tex][tex]\mathrm{The \ \underline{radius \ of \ the \ cylinder \ of \ maximum \ volume \ is \ \dfrac{8 \cdot \sqrt{6} }{3}}}[/tex]

Reasons:

The known parameter of the hemisphere are;

The radius of the hemisphere = 8

Required;

The radius and height of the maximum volume of the inscribed cylinder.

Solution:

Let h represent the height of the cylinder, and let r represent the radius of

the cylinder, we have;

r² + h² = 8²

Therefore;

r² = 8² - h² = 64 - h²

= 64 - h²

The volume of the cylinder, V = π·r²·h = π·(64 - h²)·h

V(h) = π·(64·h - h³)

At the maximum volume, we have;

[tex]\dfrac{dV(h)}{dh} = \dfrac{d}{dh} \left(\pi \cdot \left(64 \cdot h - h^3 \right) \right) = \pi \cdot \left(64 - 3 \cdot h^2 \right) = 0[/tex]

64 - 3·h² = 0

64 = 3·h²

[tex]h =\sqrt{\dfrac{64}{3} } = \dfrac{8}{\sqrt{3} }[/tex]

[tex]\underline{\mathrm{The \ height \ of \ the \ cylinder, \ h} = \dfrac{8}{\sqrt{3} }}[/tex]

[tex]r^2 = 64 - \dfrac{64}{3} = \dfrac{128}{3}[/tex]

[tex]r =\sqrt{\dfrac{128}{3}} = \dfrac{8 \cdot \sqrt{6} }{3}[/tex]

[tex]\underline{\mathrm{The \ radius \ of \ the \ cylinder, \ } r = \dfrac{8 \cdot \sqrt{6} }{3}}[/tex]

If and cx = 5 units, what is dz? 2 units 3 units 4 units 5 units.

Answers

Based on the calculations, the magnitude of side DZ is equal to 4 units.

How to calculate the magnitude of DZ?

From the diagram, we can deduce that CD is parallel to XZ and as such, triangle XYZ is similar to Triangle YCD. Thus, the ratio of their corresponding side lengths are equal.

By applying the similarity condition, we have:

XY/CY = ZY/YD

(XC + CY)/CY = (DZ + DY)/DY

Substituting the given parameters into the formula, we have;

(5 + 25)/25 = (DZ + 20)/20

30/25 = (DZ + 20)/20

600 = 25DZ + 500

25DZ = 600 - 500

25DZ = 100

DZ = 100/25

DZ = 4 units.

A vector makes an angle, θ, with the horizontal. The horizontal and vertical components of the vector will be equal in magnitude if θ is.

Answers

A vector has horizontal and vertical components.

The value of [tex]\mathbf{\theta }[/tex] is 45 degrees, when the horizontal and vertical components are equal

Let the magnitude of the vector be H.

So, the horizontal (h) and the vertical components (v) of the vector would be:

[tex]\mathbf{v = Hcos(\theta)}[/tex] --- vertical

[tex]\mathbf{h = Hsin(\theta)}[/tex]

Equate both expressions

[tex]\mathbf{h = v}[/tex]

Substitute values for h and v

[tex]\mathbf{Hcos(\theta) = Hsin(\theta)}[/tex]

Divide both sides by H

[tex]\mathbf{cos(\theta) = sin(\theta)}[/tex]

When [tex]\mathbf{cos(\theta) = sin(\alpha)}[/tex], then

[tex]\mathbf{\theta + \alpha = 90^o}[/tex]

So, we have:

[tex]\mathbf{\theta + \theta = 90^o}[/tex]

[tex]\mathbf{2\theta = 90^o}[/tex]

Divide both sides by 2

[tex]\mathbf{\theta = 45^o}[/tex]

Hence, the value of [tex]\mathbf{\theta }[/tex] is 45 degrees

Explanation:

Pollutants mixed with water pass through permeable layers above the aquifer.

What is Groundwater?

Water that is found underground in saturated regions beneath the surface of the earth is known as groundwater. The water table is the term for the saturated zone's upper surface.

Contrary to popular perception, underground rivers are not created by groundwater. Similar to how water fills a sponge, it fills the pores and cracks in subterranean materials like sand, gravel, and other rock.

Rock materials are referred to as aquifers if groundwater flows naturally out of them or if it can be pumped out of them. One of the most significant natural resources for the country is groundwater, which is found in aquifers beneath the Earth's surface.

Therefore, Pollutants mixed with water pass through permeable layers above the aquifer.

Answers

Answer:

The heart, the heart is what makes every moving part working inside our body even though the brain is the one who tells them or gives them signals to work. the heart is what keeps them alive and if the heart takes any kind of negative damage the would not take care of everything it's supposed to.  If the heart starts to fail it will effect the blood suply to all your body parts and blood is what carries the oxygen throughout your body and without getting the proper blood or oxygen supply to those certain body parts will have an effect like you couldn't keep warm or cool off, fight infections, or get rid of our own waste products. Without enough blood, we'd weaken and die.

Explanation: That's my answer

The body part that can be picked in the given model is heart. Any injury can affect the bloop supply throughout the body.

What is circulatory system?

Blood vessels in the circulatory system transport blood away from and towards the heart. Arteries transport blood away from the heart, while veins transport blood back to the heart.

The heart in the body is analogous to a car's engine in that it pumps oxygen carrying blood cells into all organs, and without these oxygen carrying blood cells, the entire body will stop functioning.

An injury or disease to the heart will have a negative impact on the rate of blood distribution to all parts of the body, which will have a negative impact on the overall wellbeing of the body and will also have a negative impact on the process being modeled.

Thus, the heart is the body part shown here.
