Answer:

50.24

Step-by-step explanation:

Area = 200.96

Let's find the raidus from the area formula.

200.96 =  π · r^2

Divide both sides by  π !

64 = r^2

square root both sides

r = 8.

Now since we know the raidus we can find the circumferewnce.

-

c=2πr

c=2*3.14*8

c= 50.24

Answer:

f(-3) = -26

Step-by-step explanation:

To find the answer plug -3 in for every x in the equation. Like this:

[tex]-2(-3)^{2} +5(-3)+7[/tex]

Now, simplify:

-2(9) - 15 + 7                 Square -3.

-18 - 15 + 7                    Multiply -2 by 9.

-26                                Simplify.

So, f(-3) = -26.

Answer:

Step-by-step explanation:

f(-3)= -2(-3)^2 + 5(-3) + 7

         -2(9) - 15 + 7

         -18 - 15 + 7

          -33 + 7 = -26

The expression is given as:

163.28 + 75.459

The expression is best solved using a calculator.

However, in the absence of a calculator, the following steps can be applied.

Expand each term

163.28 + 75.459 = 163 + 0.28 + 75 + 0.459

Reorder the terms

163.28 + 75.459 = 163 + 75+ 0.28  + 0.459

Add the decimals and integers

163.28 + 75.459 = 238.739

Hence, the result of 163.28 + 75.459 is 238.739

Answer:

x=10

y=[tex]10\sqrt{3}[/tex]

Step-by-step explanation:

Since there is a 30 degree angle, it is a special right triangle, 30 60 90 triangle. The shorter leg represents "a," the longer leg represents "a√3", and the hypotenuse represents 2a.

The triangle has a hypotenuse of 20 and we are trying to find x and y. x=10 because x is the opposite side of 30 degrees and x is half of the hypotenuse. y=[tex]10\sqrt{3}[/tex] because we already know the x value and y is opposite of 60 degrees. As mentioned before, the longer leg represents a√3.

Answer:

D. The person who tells the story

Step-by-step explanation:

The narrator is the person telling the story, or the voice that an author takes on to tell a story.

The person who reads the story is simply a reader. They aren't narrating.
Someone who says all of the dialouge isn't a narrator either, because only saying the dialouge excludes the rest of the story. It's not telling the story.
The person who writes the story is the author, not the narrator.

Therefore, option D makes the most sense.

1 and 125, 5 and 25

Step-by-step explanation:

Any two numbers that multiply to 125 could be considered as the length and width. Because the formula is: A=wl.

Answer:

-0.5.

Step-by-step explanation:

2pi - 11pi/6 = pi/6

so the angle is in the fourth quadrant  where the sine is negative.

pi/6 = 30 degrees and we know form the 30-60-90 triangle that sin 30 = 0.5,

therefore sin pi/6 = 0.5

and sin 11pi/6 = -0.5

The exact value of sin(11π/6) radians is -1/2 by using unit circle

To find the exact value of sin(11π/6) radians, we can use the unit circle and trigonometric identities.

The angle 11π/6 radians is in the third quadrant of the unit circle.

In the third quadrant, the sine function is negative.

We can find the reference angle by subtracting 2π (or 12π/6) from the given angle:

11π/6 - 12π/6 = -π/6

The reference angle is -π/6 radians.

In the unit circle, the coordinates for the angle -π/6 are (√3/2, -1/2). The y-coordinate represents the value of sine.

Therefore, the exact value of sin(11π/6) radians is -1/2.

The radius of a cylindrical gift box is ​(3x+2​) inches. The height of the gift box is twice the radius. The surface area of the​ cylinder is 54πx² + 84πx + 32π square inches.

The surface area of a cylinder is given as:

2πr(r + h)

The radius of a cylindrical gift box is ​(3x+2​) inches. The height of the gift box is twice the radius.

We need to find the surface area of the​ cylinder.

The radius of a cylindrical gift box is ​(3x+2​) inches.

The height of the gift box is twice the radius = 2(3x + 2) inches

= 6x + 4 inches

The surface area of the cylinder is:

= 2 × π × (3x + 2)( 3x + 2 + 6x + 4) square inches

= 2 × π × (3x + 2)(9x + 8) square inches

= 6πx + 4π( 9x + 8) square inches

= 6πx (9x + 8) + 4π( 9x + 8) square inches

= 54πx² + 48πx + 36πx + 32π square inches

= 54πx² + 84πx + 32π square inches

Hence, The surface area of the​ cylinder is 54πx² + 84πx + 32π square inches.

The percentage of the runner from team B that finishes the race is 21.4%

How to find the percentage that finish the race from team B?

Team A and Team ran a race. Team A had 28 runners and Team B also had 28 runners.

4 runners from team A finishes the race while 12 runners from team B finishes the race.

Therefore, the percentage from team B that finishes the race can be calculated as follows.

percentage from team B that finishes = 12 / 56 × 100

percentage from team B that finishes = 1200 / 56

percentage from team B that finishes = 21.4285714286

Answer:

[tex]10x^{3}+x^{2} -1[/tex]

Step-by-step explanation:

Standard form means firstly you will combine like terms (which the problem has already done) and then rewrite the polynomial from greatest power to least power.

We have three separate parts to this polynomial:

The part that has the greatest power is [tex]10x^{3}[/tex]. This is because the x is multiplied by a power of 3, which is the largest power given. Next up would be [tex]x^{2}[/tex]. Finally, -1 would come last.

Thus, the rewritten equation should look like this:

Median is between 18 and 23 so we add them then divide the sum by 2

Median: (18 + 23)/2 = 20.5

First Quartile is between 10 and 13 so we add them then divide the sum by 2

First Quartile: (10 + 13)/2 = 11.5

Third Quartile is between 25 and 26 so we add them then divide the sum by 2

Third quartile: (25 + 26)/2 = 25.5
