A cylinder has a base diameter of 8 centimeters and a height of 7 centimeters.what is its volume in cubic centimeters,to the nearest tenths place

Answers

Answer 1
56 cubic centimeters
Answer 2

The volume of the cylinder is approximately 351.9 cubic centimeters.

What is a cylinder?

A cylinder is a 3-D figure that has a radius and a height.

The volume of a cylinder is given as πr²h.

Example:

The volume of a cup with a height of 5 cm and a radius of 2 cm is

Volume.

= 3.14 x 2 x 2 x 5

= 62.8 cm³

We have,

The volume of a cylinder can be calculated using the formula:

V = πr²h,

where r is the radius of the base and h is the height.

Since the base diameter is given as 8 centimeters, the radius is half of that or 4 centimeters.

Substituting these values into the formula, we get:

V = π (4 cm)² (7 cm)

V ≈ 351.86 cm³

Rounding this answer to the nearest tenth gives a final answer of V ≈ 351.9 cm^3.

Therefore,

The volume of the cylinder is approximately 351.9 cubic centimeters.

If Candace made a scatter plot of the math scores of eighth-grade students (vertical scale) and their heights in inches (horizontal scale), what type of line of best fit should she expect the scatter plot show?

A. a line with positive slope
B. a line with negative slope
C. a horizontal line
D. There would be no line of best fit.

Answers

Answer:

The correct option is (D).

Step-by-step explanation:

A scatter plot is a mathematical graph used to display the linear relationship between two variables.

Points are plotted on the graph and a line of best is drawn to represent the linear relationship between the two variables.

If the line is upward moving this implies that there is positive relation between the variables.

If the line is downward moving this implies that there is negative relation between the variables.

If there is no line of best fit that can be formed using the data provided then this implies that there is no linear relationship between the variables.

The variables math-score and height of the students has no relation between them. This is because the height of a student does not factor the score he/she received in their math exam.

So, the scatter plot for this data will not have a line of best fit.

Thus, the correct option is (D).

Math problem: There are 36 carpenters in a crew. On a certain day, 29 were present. What percent showed up for work? (round to the nearest tenth)

Answers

Answer:

10%

Step-by-step explanation:

Answer:

The percentage showed up for work is 8.556 %

● Given that total number of Carpenters is 36.

● On a certain day only 29 carpenters were present.

● To calculate the percentage we have to divide the number of carpenters present on that specific day by the total number of carpenters and multiply the product with 100 i.e., we have to divide 29 with 36 and multiply it with 100.

Percentage = (29 / 36) * 100

= (0.80556) * 100

= 80.556

● Therefore the required percentage is 80.556%

Step-by-step explanation:

To find the first 4 terms, substitute n = 1, 2, 3, 4 into the sequence rule.

For the 10 th term substitute n = 10 into the sequence rule

(a)

n = 1 → 1² + 3 = 1 + 3 = 4

n = 2 → 2² + 3 = 4 + 3 = 7

n = 3 → 3² + 3 = 9 + 3 = 12

n= 4 → 4² + 3 = 16 + 3 = 19

n = 10 → 10² + 3 = 100 + 3 = 103

Thus the first 4 terms are 4, 7, 12, 19 and term 10 is 103

------------------------------------------------

(b)

n = 1 → 2 × 1² = 2 × 1 = 2

n = 2 → 2 × 2² = 2 × 4 = 8

n = 3 → 2 × 3² = 2 × 9 = 18

n = 4 → 2 × 4² = 2 × 16 = 32

n = 10 → 2 × 10² = 2 × 100 = 200

Thus the first 4 terms are 2, 8, 18, 32 and term 10 is 200

The question is : Find the volume of the figure above ​

Answers

Answer:

985.31 cm² is the volume of the figure.

Step-by-step explanation:

First, find the volume of the cylinder

[tex]V=\pi r^{2} h[/tex]      Use this equation to find the volume of the cylinder

[tex]V=\pi (4)^{2} (20)[/tex]     Simplify the exponent and multiply

[tex]V = 320\pi[/tex]            Multiply

1005.31 cm² is the volume of the cylinder

Next, find the volume of the rectangle

V = L x W x H     Use this equation to find the volume of the rectangle

V = 20 x 1 x 1      Multiply

V = 20 cm² is the volume of the rectangle

Subtract the volume of the rectangle from the volume of the cylinder to find the volume of the figure.

1005.31 cm² - 20 cm² = 985.31 cm² is the volume of the figure.

Answer:

I had 271.36cm^3

Step-by-step explanation:

There are 2 figures in the diagram above a cylinder and a cuboid if I'm right

So volume of Figure = V(cylinder) + V(cuboid)

V(cylinder) =pi x rxr xh

Pi=3.142, radius is 2 (since diameter is 4cm), height is 20cm.

So V(cylinder) =3.142x4x20 = 251.36cm^3

V(cuboid) =lbh =1x1x20 =20cm^3

So V(figure)= 20+251.36

=271.36cm^3

Answers

Answer:

8/45

Step-by-step explanation:

1. Since the dice has six sides and only two numbers are less than three (2 and 1) that means there is a 4/6 (2/3) chance of them rolling any other number besides 2 and 1. Since in bag two it has the yellow dice.

2. In bag two there are a total of 15 beads (4 yellow and 11 blue) since we want to get the yellow bead that means there is a 4/15 chance of getting a yellow bead.

3. Finally to find the chance of rolling a number greater than 2 and picking a yellow bead you must multiply the numerators and denominators. 2(4) and 3(15) which in turn equals 8/45.

Please Answer !! A store is having a sale on almonds and jelly beans. For 5 pounds of almonds and 3 pounds of jelly beans, the total cost is $23. For 2 pounds of almonds and 6 pounds of jelly beans, the total cost is $20. Find the cost for each pound of almonds and each pound of jelly beans.

Answers

Answer:Let x = number of pounds of jelly beans

      y = number of pounds of almonds.

 

Then, 4x + 8y = 33

          2x + 3y = 13

 

Multiply the second equation by -2 to get the system:

 

4x + 8y = 33

-4x - 6y = -26

 

Adding the equations, we get 2y = 7.  So, y = 3.5

 

Substitute for y in either of the given equations:  2x + 3(3.5) = 13

                                                                                     2x + 10.5 = 13

                                                                                                 2x = 2.5

                                                                                                   x = 1.25

0>) 48 ounces
1) 60 ounces
(3) 19 ounces
) 30 ounces

Answers

Answer:

the first one

Step-by-step explanation:

1 pound equals 16 ounces.

The total number of ounces that it will weight is 48.

What are ounces ?

"The ounce is the name of several different units of mass, weight or volume and is derived almost unchanged from the uncia, an Ancient Roman unit of measurement.

The avoirdupois ounce (exactly 28.349523125 g) is 1⁄16 avoirdupois pound; this is the United States customary and British imperial ounce. It is primarily used in the United States to measure packaged foods and food portions, postal items, areal density of fabric and paper, boxing gloves, and so on, but it is sometimes also used elsewhere in the Anglosphere."

Given,

Number of pounds = 3

[tex]1 pound = 12 ounces[/tex]

So, 3 pound = 12*3 = 48 ounces

Hence, option A is the correct option.
