Answer:

The circumference is 44 pi.

Step-by-step explanation:

You have to use the formula, C=2 Pi R but since it's in terms of pi, we can not include pi in the equation. 2 times r (radius) is 44, therefor the answer is 44 pi.

What is the volume of the sphere that has a diameter of 3? use 3.14 for pie

aev [14]

Hey ! there

Answer:

113.04 unit cube

Step-by-step explanation:

In this question we are provided with a sphere having radius 3 units and value of π is 3.14 . And we're asked to find the volume of sphere .

For finding volume of sphere , we need to know its formula . So ,

$\qquad \qquad \: \underline{\boxed{ \frak{Volume_{(Sphere)} = \dfrac{4}{3} \pi r {}^{3} }}}$

Where ,

π refers to 3.14

r refers to radius of sphere

Solution : -

Now , we are substituting value of π and radius in the formula ,

$\quad \longrightarrow \qquad \: \dfrac{4}{3} \times 3.14 \times (3) {}^{3}$

Simplifying it ,

$\quad \longrightarrow \qquad \: \dfrac{4}{3} \times 3.14 \times 3 \times 3 \times 3$

Cancelling 3 with 3 :

$\quad \longrightarrow \qquad \: \dfrac{4}{ \cancel{3}} \times 3.14 \times 3 \times 3 \times \cancel{3}$

We get ,

$\quad \longrightarrow \qquad \:4 \times 3.14 \times 9$

Multiplying 4 and 3.14 :

$\quad \longrightarrow \qquad \:12.56 \times 9$

Multiplying 12.56 and 9 :

$\quad \longrightarrow \qquad \: \pink{\underline{\boxed{\frak{113.04 \: unit \: cube}}}} \quad \bigstar$

Henceforth , volume of sphere having radius 3 units is 113 .04 units cube .

Nataliya [291]

Answer:

It is the last graph: solid line, shaded area over the line x = 2 - x/2

Explanation:

1) Set the algebraigic expression that represents the combinations of sofa and pillow orders:

Number of sofas: x (given)
Number of pillows: 2y (given, since they come in pairs)
Number of items = number of sofas + number of pillows = x + 2y
Minimum of 4 items in each order (given) ⇒ x + 2y ≥ 4

2) Predict the graph of the inequality x + 2y ≥ 4

The border line is the equation x + 2y = 4
You can choose two points to draw a line
Choose the axis-intercepst:

x = 0 ⇒ 2y = 4 ⇒ y =4/2 ⇒ y = 2 ⇒ point (0,2)

y = 0 ⇒ x = 4 ⇒ point (4,0)

Then the lines goes through (0,2) and (4,0) ... [the four graphs meet this]

The shading area is above the line because when you solve for y you get y ≥ 2 - x/2, and the line is included because the "equal to" part of the symbol (≥ means greater than or equal to).

To state that the line is included the graph uses a continous line instead of a dotted one.

3) Conclusion:

That means that the correct graph is the last one: solid line, shaded area over the line y = 2 - x/2.

Note: a more detailed graph would include the fact that the items cannot be negative, i.e. x ≥ 0 and y ≥ 0, which would result in that the shaded area would be on the first quadrant.

Answer:

The correct answer is D...

Step-by-step explanation:

In order to find the distance of the diagonals, you would need to use the distance formula...

The square root of (x2-x1)^2 + (y2-y1)^2

After you plug in the letters into the appropriate places you should get the square root of (a+b)^2 +c
