What is the volume of the cylinder below? a cylinder with a height of 12 millimeters and diameter of 18 millimeters. 108 pi mm3 216 pi mm3 648 pi mm3 972 pi mm3

Answers

The volume of a cylinder with a height of 12 millimeters and diameter of 18mm is 972π mm^3

Volume of a cylinder

The formula for calculating the volume of a cylinder is expressed as:

V = πr²h where:

r is the radius

h is the height

Given the following parameters

h = 12mm

r = 18/2 = 9mm

Substitute

V = π(9)²(12)
V = 972π mm^3

Hence the volume of a cylinder with a height of 12 millimeters and diameter of 18mm is 972π mm^3

Enter your answer as a decimal in the box. Round only your final answer to the nearest hundredth.

Answers

Answer:

  29.05°

Step-by-step explanation:

The mnemonic SOH CAH TOA is intended to remind you of the relationship between trig functions and side lengths in a right triangle. In your triangle, the sides adjacent and opposite angle D are given. The relevant relation is ...

  Tan = Opposite/Adjacent

__

Using the given values, we have ...

  tan(D) = (25 ft)/(45 ft) = 5/9

The value of the angle is found using the inverse tangent function.

  D = arctan(5/9) ≈ 29.05°

The measure of angle D is about 29.05°.

The area of a rectangle is 48 cm². If its width is 6 cm, what is its length?

AREA

================================

[tex] \large \sf \underline{Question:}[/tex]

The area of a rectangle is 48 cm². If its wdth is 6 cm, what is its length

================================

[tex] \large \sf \underline{Answer:}[/tex]

[tex] \qquad \qquad \qquad \huge \bold{8cm}[/tex]

To solve for the area of rectangle, you use this formula A = length × width. But we're doing it reversal, we will divide the width to the area

[tex]\large\tt{A \: = \: l \: \times \: w}[/tex]

[tex]\large\tt{48cm^{2} \: = \: l \: \times \: 6cm}[/tex]

[tex]\large\tt{48cm^{2} \: \div \: 6cm \: = \: l}[/tex]

Therefore, The length is 8cm.

================================

Hey ! there

Answer:

Length of rectangle is 8 cm .

Step-by-step explanation:

In this question we are provided with a rectangle having area 48 cm² and width 6 cm . We are asked to find the length of rectangle .

We know that ,

[tex] \qquad \qquad\underline{\boxed{\frak{Area_{(Rectangle)} = l \times w}}}[/tex]

Where ,

l refers to Length

w refers to Width

SOLUTION : -

We are finding value of length by substituting value of width as 6 cm and area as 48 cm² in the formula . So ,

[tex] \quad\longmapsto \qquad \:48 = 6 \times l[/tex]

or ,

[tex] \quad\longmapsto \qquad \:48 = 6l[/tex]

Dividing with 6 on both sides :

[tex] \quad\longmapsto \qquad \: \cancel{\dfrac{48}{6}} = \dfrac{ \cancel{6}l}{ \cancel{6}} [/tex]

We get ,

[tex] \quad\longmapsto \qquad \: \orange{\underline{\boxed{ \frak{l = 8 \: cm}}}} \quad \bigstar[/tex]

Henceforth , Length of rectangle having area 48 cm² and width 6 cm is 8 cm

Verifying : -

We are verifying our answer by substituting value of length and width in formula and equating it with given area . So ,

[tex] 8 \times 6 = 48[/tex]

[tex]48 = 48[/tex]

[tex] \rm{L.H.S = R.H.S}[/tex]

[tex] \rm{Hence , \: Verified .}[/tex]

Therefore , our answer is correct .

In a survey of adults, 18% lift weights regularly, 32% run regularly, and 7% lift weights and run regularly. What is the conditional probability that an adult who lifts weights regularly, also runs regularly?

Answers

The conditional probability that an adult who lifts weights regularly, also runs regularly is 0.219 or 21.9% if the 18% lift weights regularly, 32% run regularly, and 7% lift weights and run regularly.

What is probability?

It is defined as the ratio of the number of favorable outcomes to the total number of outcomes, in other words the probability is the number that shows the happening of the event.

Let's suppose P(A) is the probability of adults who lift weights regularly.

P(A) = 18% = 0.18

Similarly,

P(B) = 32% = 0.32

P(A∩B) = 0.07

We know:

[tex]\rm P(A|B) = \dfrac{P(A\cap B)}{P(B)}[/tex]

[tex]\rm P(A|B) = \dfrac{0.07}{0.32}[/tex]

P(A|B) = 0.219  or

P(A|B) = 21.9%

Thus, the conditional probability that an adult who lifts weights regularly, also runs regularly is 0.219 or 21.9% if the 18% lift weights regularly, 32% run regularly, and 7% lift weights and run regularly.

b. What is the experimental probability that there will not be 200 or

eleventh day?


Can someone please help I’m stuck ( and please show the work) thank you.

Answers

Event=200 or more cars

The number of cars was counted on 10 days and thus there were 10 trials.

# of trials=10

200 or more cars were counted on 9 of the 10 days and thus the event occurs 9 times.

# of times the event occurs= 9

The probability is the number of times the event occurs divided by the number of trials:

P ( 200 or more cars)= # of times the event occurs / # of trials

=9/10
0.9
90%

We know that the sum Of the probabilities Of an event And it’s Complement needs to be equal to 1.

P( event ) + P ( complement)= 1

What is it is “200 or more cars”

P( 200 or more cars) + P (not 200 or more cars) = 1

Since P ( 200 or more cars) = 9/10 we can replace P ( 200 or more cars) in the equation by 9/10

9/10 +P ( not 200 or more cars) =1

Subtract 9/10 from each side

-9/10= 1-9/10

Combine like terms

P( not 200 or more cars) = 1/10= 0.1 = 10%

A: 9/10 = 0.9 = 90%
B: 1/10= 0.1= 10%

Jacob earned a gross pay for the week of $592. If 16% was withheld for deductions, what was his net pay?

Answers

Answer:

$497.28

Step-by-step explanation:

First, you need to find 16% of 592. To do this, turn 16% into a decimal by dividing by 100:

16/100 = 0.16

Then, multiply 0.16 by 592, to get 94.72.

Then, subtract this number from 592:

592 - 94.72 = 497.28

Which of the following units could be used to measure Area? Select all that apply.


a) m2

b) in

c) cm2


d) sq. ft

e) mm

f) yd3

Answers

All the area measure units should have square above them.

For example:mm²cm²yd²in²m²km²ft²

Hence, option A, C, D is correct.

Answer:

a) c) d)

Step-by-step explanation:

Length is a one-dimensional measure, therefore it is measured in single units.

⇒ m

⇒ cm

⇒ ft

The area of a shape is a two-dimensional quantity (e.g. length × width), therefore it is measured in square units.

⇒ m × m = m²

⇒ cm × cm = cm²

⇒ ft × ft = ft²

The volume of a shape is a three-dimensional quantity (e.g. length × width × height), therefore it is measured in cubic units.

⇒ m × m × m = m³

⇒ cm × cm × cm = cm³

⇒ ft × ft × ft = ft³

Therefore,

length = options b) e)area = options a) c) d)volume = option f)

Answers

If he doubles his speed when he sees his friends ahead of him. his kinetic energy at the faster speed is joules is 160Joules

Kinetic energy of an object.

The formula for calculating the kinetic energy of an object is expressed as:

KE = 1/2mv²

where:

m is the mass of an object

v is the velocity

If he’s moving at 2 meters/second and has 40 joules of kinetic energy, the mass is calculated as:

40 = 0.5(2)²m

40 = 2m
m = 20 kg

If he doubles his speed when he sees his friends ahead of him, his kinetic energy will be:

KE = 0.5(20)(4)²
KE = 10*16
KE = 160joules

Hence if he doubles his speed when he sees his friends ahead of him. his kinetic energy at the faster speed is joules is 160Joules
