A cylinder shaped soap dispenser has a diameter of 4 in. and has a height of 7 in.

What is the approximate volume of the soap dispenser? Use 3.14 for π.

You may use your formula sheet and a calculator.

Question 3 options:

351.68 in³


87.92 in³


175.84 in³


95.18 in³

Answers

Answer 1

Answer:

87.92 in^3

Step-by-step explanation:

Formula for finding the volume of a cylinder:

V=Bh

B= area of the base

h= height

Diameter=4 radius=2 The radius is half of the diameter

The base of a cylinder is a circle, so you would find the area of the circle and multiply it by the height of the cylinder.

V= (3.14*2^2)7

V= (3.14*4)7

V= 12.56(7)

V= 87.92 in^3

Answer 2

Answer:

The answer to this question should be b. 87.92 in^3 because the formula to find the volume of a cylinder is V=TTr^2h. and remember that the radius is half of the diameter so back to the question.

We multiplied 3.14 times 4 because remember that the radius is half of the diameter and we get 2 but remember the exponent so we need to multiplied to the second power 2 times 2 and we get 4 so when we multiplied 3.14 times 4 we get 12.56 and when we multiplied 12.56 times the height which is 7 we get 87.92 so check the choices and see if there is an answer and yes there is so b which is 87.92in^3 is hopefully the correct answer.

Step-by-step explanation:

Start with the face of your 3D shape, which has a length/width of 3 units and a height of 4 units. Then look at the visible side of your figure, in this case it is the right side. You can see it's width/length of 2 units, so multiply 4x3x2, and in this case 4x3=12 and 12x2 is 24. making your answer 24 units cubed.

The Smiths have a​ rectangular, above-ground swimming pool. The manufacturer says that the pool holds​ 14,040 gallons of water when filled to capacity. After it is​ filled, Mr. Smith follows the​ manufacturer's recommendation of adding 1 ounce of chlorine for every​ 2,700 gallons of​ water, every other day. About how many pounds of chlorine will Mr. Smith add to the pool in 3​ weeks?

Answers

Answer:

54.6 ounces

Step-by-step explanation:

14,040/2,700=5.2

3 weeks is 21 days

21 days divided by 2 because every other day is 10.5 days

5.2 times 10.5 is 54.6

54.6 ounces because 14,040 divided by 2,700 you will get 3 week and the 21 days so you would do is 21 days divided by 2 because every other day is 10.5 days. So, than 5.2 *10.5 is 54.6.

Answers

The number of the blue leashes will be 240.

What are linear equations?

It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.

It is given that:-

A pet shop owner bought 320 leashes. 30% of these leashes were pink leashes and the rest were blue and green leashes.The number of blue leashes is 3 times the number of green leashes.

The number of the blue leashes will be calculated as:-

L     =    320

B   +    P   +   g   =   320

{ (320  x   0.3 ) } + 0.7 ( B  +  g ) =  320

( 96 )  +   ( 2.8g )   =   320

2.8g   =   320 / 96

g   =   222  /  2.8  =  80

Now  B  =   3  x  g

B   =   3   x   80

B   =   240

Therefore the number of the blue leashes will be 240.

Step-by-step explanation:

Finding the Surface Area :

Area (2 triangles) + Base rectangle + Left rectangle + Right rectangle2 x 1/2 x 4 x 5 + 9 x 5 + 6 x 9 + 5 x 920 + 45 + 54 + 4565 + 99164 cm²

Step-by-step explanation:

just take a deep breath, shake your limbs, and then focus on it again.

the surface consists of 5 areas :

front and back triangles (2)

left rectangle

right rectangle

floor rectangle

the area of a rectangle is simple :

length × width

the area of a triangle is

baseline × height / 2

each of the front and back triangles has an area of

5 × 4 / 2 = 5×2 = 10 cm²

both of them have then 10×2 = 20 cm²

the left rectangle is

9×6 = 54 cm²

the right rectangle is

9×5 = 45 cm²

the floor rectangle is also

9×5 = 45 cm²

so, the total surface area is

20 + 54 + 45 + 45 = 164 cm²

of the numbers represent a day without rain. Then, perform multiple trials, generating
random numbers for each trial.

Answers



answer: The experimental probability that it will not rain on any pf the next 3 day is 64/125


The probability of raining is 20%
Hence, the probability that there will be no rain, is (100-20) = 80%
The probabilty that there is no rain on the first day is 80/100 = 4/5


Hence, the required probaility is (4/5)3 = 64/125

Describe how you would use unit cubes to determine the volume of the rectangular prism below. What is the volume of the rectangular prism? A cube that is five inches in length width and height.

Answers

Answer:

Unit Cubes = 125 in

Volume = 125 in

Step-by-step explanation:

To find the volume of a rectangular prism, we multiply the length of the prism by the width of the prism by the height of the prism.

Volume of rectangular prism = length x width x height

Advance explanation:

The formula to find the volume of the rectangular prism is this:

L x W x H = V

L = Length = 5 in

W = Width = 5 in

H = Height = 5 in

V = Volume = 125

You first need to multiply the Length with the Width then multiply the Length and Width with the height (5 x 5 x 5), after that your answer will be 125 In

Hope this helps!

Summarized Steps:

Multiply the Length and Width with the Height (L x W x H).Your answer will be the result of the equation.
