This composite figure is made of three identical cylinders that are connected together

Radius:3 Height:8

Answers

Answer 1
The surface are of a cylinder is

SA = 2πr2 + 2πrh

where:
r = radius
h = height

This formula comes from adding the areas of the surfaces of the cylinder. It has two flat circular faces and a rounded face.

If we cut the cylinder from the circular face symmetrically, the surface area for one piece will be

SA = 2[(πr2)/2] + (2πr/2)h + 2rh

We will have 2-half flat circular faces, a flat rectangular surface, and half of the rounded surface.

Simplify the SA formula.

SA = πr2 + πrh + 2rh
SA = r(πr + πh + 2h)

Substitute the values into this formula.

SA = 3(3π + 8π + (2*8))
SA = 3(11π + 16)
SA = 33π + 48
SA = 151.67 cm2

Since we have 2 pieces, multiply this result by 2.

2(151.67 cm2) = 303.34 cm2.

The total area is 303.34 cm2.

[[Please Explain]] The equation y - 2/3 = -2 (x - 1/4) is written in point-slope form. What is the equation in slope-intercept form? ³
O y = -2x - 1/6
O y = -2x + 7/6
O y = -2x + 5/12
O y = -2x - 11/12

Answers

Slope-intercept form is just solving for y in point-slope form

y - 2/3 = -2 (x - 1/4)

First you distribute the -2 because it is the first order of operation

y - 2/3 = -2x + 1/2

Then you add 2/3 on both sides because we want to isolate y

y = -2x + 1/2 + 2/3

Then we combine like terms

y = -2x + 7/6

What is (4/9)^2?
What is 4 over 9(as a fraction) to the power of 2?

Answers

Answer:

16/81

Step-by-step explanation:

To square a fraction, you would have to square both the denominator and the numerator. You would have to do 4x4/9x9, which is 16/81.

Answer:    

The answer is 16/81

Step-by-step explanation:

To evaluate this equation first find a understanding of what needs to be solved.

Here we see that we need to solve 4/9th to the power of 2.

to solve this we find what 4 to the power of 2 is and what 9 to the power of 2 is.

To use the power of 2 you multiply the number to itself that many times so if its 5 to the power of 3 you would right it as 5 x 5 x 5.

In this case we need to do 4 x 4 and 9 x 9.

4 x 4 = 16

9 x 9 = 81

The 4 x 4 solution remains as the numerator

The 9 x 9 solution remains as the denominator

After solving we get 16/81, due to the 81 not being even and 16 not being a multiple we can not simplify this fraction anymore.

The correct answer is 16/81 have a great day :)

Vivian would have 7 carrots left to spare if she ate 65% of the carrots in the bag.

which expression has a value of 6 when x=2 and y=4?

Answers

B
refer to picture for steps
Answer:6Verification:

Let's verify all the options to the question. Clue given: x = 2, y = 4

Option A:

(x² + 8) ÷ y - 2

=> (2² + 8) ÷ 4 - 2

=> (4 + 8) ÷ 4 - 2

=> 12 ÷ 4 - 2

=> 3 - 2

=> 1 ≠ 6

This answer does not equal 6.

Option B:

(x² + 8) ÷ (y - 2)

=> (2² + 8) ÷ (4 - 2)

=> (4 + 8) ÷ (4 - 2)

=> 12 ÷ 2

=> 6 = 6

This answer is correct as 6 = 6.

Option C:

x² + 8 ÷ (y - 2)

=> 2² + 8 ÷ (4 - 2)

=> 4 + 8 ÷ 2

=> 4 + 4

=> 8 ≠ 6

This answer does not equal 6.

Option D:

x² + 8 ÷ y - 2

=> 4 + 8 ÷ 4 - 2

=> 4 + 2 - 2

=> 4 ≠ 6

This answer does not equal 6.

So, after verifying all our options, we can conclude that Option B is correct. Therefore, Option B is the correct answer.

Veronica lives on a straight road that goes east and west. She starts from a point 5.1 miles west of her home and drives a certain distance to the store. The store is more than 3 1/2 miles east of her home. Let d represent the distance Veronica drove. Which inequality represents this situation?

Answers

Its C  because  3 1/2 is grater than -5.1 because it is negative

The inequality is −5.1 + d > 3 1/2 which represents the situation, where d represents the distance Veronica drove.

What is inequality?

Inequality is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are not equal.

Veronica lives on a straight road that goes east and west.

Let d represents the distance Veronica drove.

She started from a point 5.1 miles west of her home and drives a certain distance to the store.  

So, she drives:

−5.1 + d

The store is more than  4 1/2 miles east of her home.

Therefore, the inequality that represents the situation is as follows:

−5.1 + d > 3 1/2

Hence, the correct answer would be an option (C).

What is the coordinate plane?

A coordinate plane is a two-dimensional plane formed by the intersection of two number lines.

Given that, there is a point in quadrant IV that is 4 units away from point (-1.5, -2.5) on the coordinate plane.

If we have a coordinate point (x, -y) in quadrant 4, if the coordinate is 4 units away, the resulting coordinate will be expressed as (x+4, y-4)

(-1.5+4, -2.5-4) = (2.5, -6.5)

What would you divide the numerator and denominator by to put 16/24 in simplest form?

Answers

Answer:

8

Step-by-step explanation:

if you divide the numerator by 8 you get 2 and divide the denominator by 8 and you get 3

the simplest form would be 2/3 which was divided by 8

Answer:

Divide both numerator and denominator by 8.

Step-by-step explanation:

Firstly, find the greatest common factor (GCF) of both values.

16: 1, 2, 4, 8, 16

24: 1, 2, 3, 4, 6, 8, 12, 24

The GCF of both values is 8.

Now divide, [tex]\frac{16}{24}[/tex] ÷ [tex]\frac{8}{8}[/tex] to get the final value of [tex]\frac{2}{3}[/tex].

Simplest value is 2/3.
