Volume of a cylinder = pi x radius^2 x height of cylinder and diameter/2 is the radius so...

3.14 x (8.4/2) ^ 2 x 10 = 553.9

Since there is a hole that means you have to find the volume of the hole and subtract that from the volume of the whole pipe (553.9)

3.14 x (6/2) ^2 x 10 = 282.6

553.9 - 282.6 = 271.3

Answer:

271.3mm

Step-by-step explanation:

d=8.4

h=10

r=4.2

A=(3.14(4.2^2)) 10

A=554.176944093

d=6

h=10

r=3

A=(3.14(3^2)) 10

A=282.743338823

Now you're going to want to subtract the second area from the first area to get the leftover amount.

554.176944093 - 282.743338823 =271.433661177

~271.3mm

8. Which of these is not an integer 6 6 A 3 C E 3
Mnenie [13.5K]
An integer is a whole number. 

The answer isn't A, because 6/3=2 and 2 is a whole number.

The answer isn't C, because 6/2=3, and 3 is a whole number.

The answer therefore has to be B, because 3/6=1/2 and 1/2 isn't a whole number or an integer.

The graph shows the relationship between the number of minutes Maria spent jogging on a treadmill and the distance she jogged.
alina1380 [7]

Answer:

  0.1 miles per minute

The line goes through (0, 0), so Maria's speed is the ratio of miles to minutes:

  (4.5 mi)/(45 min) = 0.1 mi/min

what are the mean variacne and standard deviatioon of the values? round to the nerates tenth. 11,11,3,1,11
alexdok [17]

Answer:

Mean = 8

Variance = 22

Standard deviation = 4.6904

Step-by-step explanation:

To find out Mean the formula is : total sum of data set / number of values

(11 + 11 + 3 + 1 + 11 + 11) / 6 = 48 / 6 = 8

Mean = 8

Now for variance we will form a table

x                  11     11     3      1      11      11

(x - Mean)    3     3    -5     -7      3      3  

(x - Mean)²   9     9    25    49    9      9

Now we the formula of variance =

Variance = (9+9+25+49+9+9)/(6-1) = 110/5 = 22

Variance = 22

Now we know Standard deviation = √(variance)

Therefore standard deviation = √22 = 4.6904

Hope this helps!<3

andreyandreev [35.5K]

The next five sequence based on the information about the square will be 36, 49, 64, 81 and 100.

<h3>How to illustrate the information?</h3>

From the information, it was stated that an ancient culture labeled certain numbers as square numbers and that the numbers 1, 4, 9, 16, 25, and so on are square numbers.

It should be noted that the number given are squares of 1,2,3...

Therefore, the next five sequence will be:

6 × 6 = 36

7 × 7 = 49

8 × 8 = 64.

9 × 9 = 81

10 × 10 = 100

rachel is frosting the top of two cakes and wants to know which cake will require more frosting. one cake is round with a diamet
Jet001 [13]

Answer:

The square cake is has a larger area by about 40.73 square inches

Step-by-step explanation:

Find the area of the top of each cake.

The square cake has an area of 81 sq inches,   ( length x width = Area, the

                                                                                    length is 9)

The round cake has an area of 16π, which is about 50.27 square inches

  (A = πr², here r is 4, radius is half the diameter)

81 - 16π =  81 - 50.27 =  40.73 square inches
