The area of a circle is 49π in². What is the circumference, in inches? Express your answer in terms of \piπ.

Answers

Answer 1

area of circle =  π r²

π r²= 49 π

r²= 49             r= √49                  r= 7

circumference of circle = 2 π r

                                       = 2×7 × π

                                       = 14 π

Answer 2

The circumference of a circle is 14π.

What is a circle?

A circle is a two-dimensional figure with a radius and circumference of πr.

The area of a circle is πr².

We have,

Area of a circle = 49π in².

Area of a circle = πr²

Now,

πr² = 49π

r² = 49

r = 7

Now,

Circumference of a circle.

= 2πr

= 2π x 7

= 14π

Thus,

The circumference of a circle is 14π.

Please help!!!! The roots of x^2-2x-2=0 are A.1+square root of 3 B.1+square root of 12 or C.No real roots

Answers

Answer:

A

Step-by-step explanation:

We have the equation:

[tex]x^2-2x-2=0[/tex]

We can use the quadratic formula. In this case, a = 1, b = -2, and c = -2. Hence:

[tex]\displaystyle x=\frac{-(-2)\pm\sqrt{(-2)^2-4(1)(-2)}}{2(1)}[/tex]

Evaluate:

[tex]\displaystyle x=\frac{2\pm\sqrt{12}}{2}[/tex]

Simplify:

[tex]\sqrt{12}=\sqrt{4}\cdot\sqrt{3}=2\sqrt{3}[/tex]

Hence:

[tex]\displaystyle x=\frac{2\pm2\sqrt{3}}{2}[/tex]

Divide:

[tex]x=1\pm\sqrt3[/tex]

A movie theater sells out 7 times per month. Chloe counted 168 sellouts at the theater. How long was Chloe recording sales?
A. 7 years
B. 2 years
C. 1 year
D. 24 years

More questions will be asked in the comments

Answers

Answer:

B. 2 years

Step-by-step explanation:

use y = mx + b

y = total number of sell outs = 168

m = sell outs per month = 7

x = months

b is not needed for this

168 = 7x

divide both sides by 7

x = 24

divide 24 by 12 to get the number of years

years = 2

Answer:

the answer to this question is B. 2 years

Given that triangle LMN is
similar to triangle GJH, what is
the value of x?

Answers

Answer:

x = 53

Step-by-step explanation:

Similar means that the corresponding angles are congruent (the same) - basically what this means is that ∠L ≅ ∠G, ∠M ≅ ∠J, and ∠N ≅ ∠H.

Since we know that the angle measures in a triangle should add up to 180 and we know the measures of ∠L and ∠M already, we can do

180 =  67 + 60 + N

So, N = 180 - (67 + 60) = 180 - 127 = 53.

Since ∠N ≅ ∠H, ∠H = 53.

6x + 11y = - 3 → (1)

4x + y = = 17 → (2)

Multiplying (1) by 4 and (2) by - 6, then adding will eliminate the term in x

24x + 44y = - 12 → (3)

- 24x - 6y = - 102 → (4)

add (3) and (4) term by term to eliminate x

0 + 38y = - 114

38y = - 114 ( divide both sides by 38 )

y = - 3

Answer:

[tex]120x^4\sqrt{2}[/tex]

Step-by-step explanation:

First we need to break down the numbers in the radicals into its factors

so

12= 3*2*2

x³=x*x*x

Which means we have

[tex]10\sqrt{3*2*2*x*x*x}=20x\sqrt{3x}[/tex]

and

[tex]2\sqrt{2*3*x*x*x*x*x} =2x^{2} \sqrt{6x}[/tex]

Because the radicand (the small number that goes up top) are the same we can just mulitply the two from here

which means we have

[tex](20x*2x^2)\sqrt{3x*6x}=40x^3\sqrt{18x^2} \\\sqrt{18x^2}=\sqrt{2*3*3*x*x} =3x\sqrt{2} \\=120x^4\sqrt{2}[/tex]

Answer:  Area 89m^2

Step-by-step explanation:

To find the area of the rectangle we multiply

Base * Height = Area

8 * 13 = 104

Now we find the area that isn't shaded

I inference that the base of the triangle is 5m  

5 * 6 = 30

Now divide that by 2

30/2 = 15

Subtract 15 from 104

104 - 15 = 89m^2

Which of the following numbers are less than -0.625
A) -8/5
B) -5/8
C)-0.5

*Choose all that apply*

Answers

Answer:

A) -8/5

Step-by-step explanation:

First, convert -8/5 and -5/8 to decimals

-8/5 = -1.6

-5/8 = -0.625

-0.5 is greater than -0.625 because it is closer to 0.

So, the only number less than -0.625 is -8/5, which is equivalent to -1.6

So, the correct answer is A) -8/5

If a chord of a circle is 6 and is twice as far from the center chord of length 12, how long is the radius of the circle?

Answers

Answer and explanation:

A center chord in a circle is the diameter of that circle. Therefore a center chord of a circle is different from other chords that touch two points on the circle but not in the center of the circle. A diameter of a circle is the chord that runs the length of the center of the circle touching two points at the edge of the circle. A diameter is twice the radius of the circle. So if the diameter of the circle is 12cm then the radius of the circle is 6cm
