Answer:

1,017.36

Step-by-step explanation:

To find the volume of a cylinder, you need to figure out the radius and height.

We've already been given the height, which is 9 meters.

Now let's find the radius.

To find the radius you have to divide the diameter by 2, which means 12/2, which is 6.

Now let's plug it into the formula:  [tex]V = \pi r^{2} h[/tex]

So, 3.14 x [tex]6^{2}[/tex] x 9.

Solve the exponent, giving us 36.

3.14 x 36 x 9 = the volume.

Meaning, V = 1,017.36

Answer:

402.1 in^3

Step-by-step explanation:

To find the area of a cylinder, you multiply the base by the height. Given a base area of [tex]32\pi[/tex] in^2 and a height of 4 in results in the following equation:

V = 32π x 4

This comes out to be 402.123859659 which is 402.1 when rounded to the nearest tenth.

Answer:

V = 4/3 π (12)³

Step-by-step explanation:

The volume of a sphere is:

V = 4/3 π r³

where r is the radius.

Here, the ball has a diameter of 24 cm.  Radius is half the diameter, so r = 12.

V = 4/3 π (12)³

By using the Pythagorean identity the value of tan [tex]\theta[/tex] will be ∞.

tan [tex]\theta[/tex] = ∞.

Pythagorean identities are identities in trigonometry that are extensions of the Pythagorean theorem. The fundamental identity states that for any angle [tex]\theta[/tex],

[tex]sin \; ^{2} \theta + cos \; ^{2} \theta =1[/tex]

By Pythagorean Identity we have,

we have, [tex]sin \theta \; = \; -1[/tex]

So, [tex](-1)^{2} \; + \; cos^{2}\; \theta =\; 1[/tex]

[tex]\; cos^{2}\; \theta =\; 1 - \; 1[/tex]

[tex]cos^{2}\; \theta =0[/tex]

[tex]cos\; \theta =0[/tex]

Now, we know that

[tex]tan \; \theta= \frac{sin\; \theta}{cos\; \theta}[/tex]

        =  [tex]\frac{-1}{0}[/tex]

  [tex]tan \; \theta=[/tex] ∞....................... (1)

Again, tan [tex]90^{0}[/tex] = ∞

If we compare from equation (1), we have

[tex]\theta = 90^{0}[/tex]

The corresponding z score for a grade of 81.8% for a class with average grade of 83% and standard deviation of 4.2% is -0.29.

The z score is used to determine by how many standard deviations the raw score is above or below the mean. It is given by:

z = (raw score - mean) / standard deviation

Given that mean is 83%, standard deviation = 4.2%, for x = 81.8:

z = (81.8 - 83)/4.2 = -0.29

The maximum amount of money the chemistry club can spend without going over their buget is $81.4 ... With a total of 6 hours their allowed to use the room for.

Step-by-step explanation:

$49 is our constant and will not change. 5.40 however will. Let's use variable h for the amount hours they can rent the room for. Now we can make an inequality;

49+ 5.40h < 86.80

5.40h < 86.80

5.4h< 37.8

h< 7

Now that we know h will have to be less than seven for the chemistry club to spend less than their buget we can find that 6 is the maxium amount of hours they can spend in the room while staying within their budget.

The graph of y = √x is reflected in the y-axis, is horizontally stretched by a factor of 2, shifted 3 units up and 1 unit left. What is the equation of the transformed graph?

Original: y = √(x)

Reflected in the y-axis: y = √(-x)

Horizontally stretched by a factor of 2: y = √(-x/2)

Shifted 3 units up: y = 3 + √(-x/2)

And 1 unit left: y = 3 + √(-(x+1)/2)

The equation of the transformed function is y = (-5x)³.

A translation moves a shape up, down, or from side to side, but it has no effect on its appearance. A transformation is an example of translation. A transformation is a method of modifying a shape's size or position.

we have, Function

y = x³

Scale factor = 1/5

Now, stretch the function horizontally by factor 1/5 then

y = (5x)³

Now, reflection of graph about y axis result change x to -x.

y = (-5x)³

Answer:

Step-by-step explanation:

If the plane of the loop is perpendicular to the magnetic field then the θ will be zero. Then the torque will also be zero.

The torque that may cause an item to revolve along an axis is measured as torque. The axis of rotation is the point at which the item rotates.

A rectangular coil of wire, 22.0cm by 35.0cm and carrying a current of 1.95 Ampere, is oriented with the plane of its loop perpendicular to a uniform 1.50 Tesla magnetic field.

Then the torque that the magnetic field exerts on the coil will be

The torque is given as

[tex]\rm \tau = I \overrightarrow{A} \times \overrightarrow{B}[/tex]

The strength of magnetic torque on the current-carrying circle is given by θ: if θ is the angle between A and B. Then we have

[tex]\rm \tau = I AB \sin \theta[/tex]

When the loop plane is perpendicular to the magnetic field, the amplitude of magnetic torque on the current-carrying circle is zero.

Then θ = 0

Then we have

[tex]\rm \tau = I AB \sin 0\\\\\tau = 0[/tex]

Answer:

[tex]6\pi[/tex] in

Step-by-step explanation:

The formula to find the area of a circle: [tex]\pi r^{2}[/tex], where [tex]r[/tex] is the radius.

The formula to find the circumference (perimeter) of a circle: [tex]2\pi r[/tex], where [tex]r[/tex] is the radius.

1) To find the circumference of the circle, we need to find the radius ([tex]r[/tex]) first. Since the area of the circle is given to us, we need to equate this to the formula to find the area of a circle.

[tex]9\pi =\pi r^2[/tex]

Cancel the [tex]\pi[/tex] by bringing it to the other side.

[tex]9 =\pi r^2[/tex] ÷ [tex]\pi[/tex]

[tex]9 = r^2\\\sqrt{9} = r\\3 = r[/tex]

Answer:

See below

Step-by-step explanation:

π, pronounced as pi is the ratio between 2πr which is circumference to 2r which is diameter.

In word, π is circumference/diameter which has exact value of 3.14159... and it is also an irrational number too.

π is often used to be defined as 3, 3.14 or 22/7 [Keep in mind, these numbers are only approximation.] in some fields. In trigonometry, π is mostly used to refer as π radians or π rad which is equivalent to 180°.

Why do we need it? Because it’s useful in a field that requires rotation. If you notice, figure with circular base will always have π with it, the volume is an example.

In calculus, you need π to do solid of revolution method which is:

[tex]\displaystyle \large{V =\pi \int\limits^a_b {[f(x)]^2} \ dx }\\\\\displaystyle \large{V = \pi \int\limits^a_b {[g(y)]^2} \ dy}[/tex]

In trigonometry, you need it for measurement/angle.  

So anything that’s related to revolution, rotation or related to circle must require π at least.

In general life, you do not use it but this is mostly applied in engineering field and anything related to science that involves with circle or revolve.
