what is the surface area of the cylinder with height 3km and radius 7km

Answer:

x≈ 8.3

Step-by-step explanation:

ok first you have to find the hypotenuse of the smaller triangle

a²+b²=c²

2²+4²=c²

4+16=20

√20≈ 4.5

4.5²+7²=c²

20.25+49≈ 69.25

√69.25≈ 8.3

Answer:

x = [tex]\sqrt{69}[/tex]

Step-by-step explanation:

Pythagorean theorem: A^2 + B^2 = C^2

first, find the length of the line cutting through the shape:

let's call this line L.

plug the numbers into the theorem.

4^2 + 2^2 = L^2

16 + 4 = L^2

20 = L^2

next, plug 7 and L into the theorem again to find x

L^2 + 7^2 = x^2

20 + 49 = x^2

69 = x ^2

x = [tex]\sqrt{69}[/tex]

Answer:

2

Step-by-step explanation

Let's complete the square. We get:

(x^2-30x)+y^2+221=0

(x^2-30x+225)+y^2+221-225=0

(x-15)^2+y^2-4=0

(x-15)^2+y^2=4

By analyzing this, we see that the radius is just :[tex]\sqrt{4}[/tex]=2

Answer:

3 - Perpendicular.

4 - Parallel.

Step-by-step explanation:

[tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

[tex]JK = \frac{1-(-7)}{-4-(-10)} = \frac{8}{6} = \frac{4}{3}[/tex]

[tex]LM = \frac{-2-2}{-6-(-3)} = \frac{-4}{3}[/tex]

Perpendicular, because two lines are considered perpendicular if their slopes are opposite reciprocals.

[tex]JK = \frac{-2-(-2)}{3-11} = \frac{0}{-8} = 0[/tex]

[tex]LM = \frac{-2-(-7)}{1-1} = \frac{5}{0} = 0[/tex]

Answer:

-3

Step-by-step explanation:

-9 divided by +3 can be written as -9 divided by 3, because when you have a positive number, you don't have to write a plus sign in front of it. Next, we can just do 9/3 and then add the negative sign to the result to get our answer. 9 divided by 3 is equal to 3, and when you add the negative sign, you get -3.

Answer:

12500 cm

Step-by-step explanation:

0,125 km = 125 m (times 1000 because 1 km = 1000 m)

125 m = 12500 cm (times 100 because 1 m = 100 cm)

Answer: what does this say?

Answer:

$30

Step-by-step explanation:

You need to figure out how the money changes between then and now. To do that, take now and divide it by then; 900,000/30,000 = 30, the amount now is 30 times that of then. To figure out what any amount then is worth now, multiply it by 30 and you'll get you answer. (In this case: 1*30 = 30)

Answer:

2.7

Step-by-step explanation:

Answer:

2.7

Step-by-step explanation:

Step-by-step explanation:

The diameter is 6, so the square is also 6 feet by 6 feet. This means the square has an area of 36 feet.

Find the area of the circle:

3.14 * 3^2

3 ^ 2 = 9

3.14 * 9 = 28.26

Now find the area of the edges of the square.

36 - 28.26 = ~7.74 ft

Answer:

I don't know

Step-by-step explanation:

Step-by-step explanation:

In the given triangle,

Perpendicular = d

Hypotenuse = e

Base = f

We need to find the values of sinx, tanx and cosx.

We know that,

[tex]\sin \theta=\dfrac{P}{H}\\\\\tan\theta=\dfrac{P}{B}\\\\\cos\theta=\dfrac{B}{H}[/tex],

We have, P = d, H = e and base = f

So,

[tex]\sin \theta=\dfrac{d}{e}\\\\\tan\theta=\dfrac{d}{f}\\\\\cos\theta=\dfrac{f}{e}[/tex]

Hence, this is the required solution.

Using the lengths given, the Trigonometry ratios of the right triangle are:

Recall:

Given the following:

Thus:

sin x = Opp/Hyp = d/e (SOH)

cos x = adj/Hypo = f/e (CAH)

tan x = Opp/Adj = d/f (TOA)

Therefore, using the lengths given, the Trigonometry ratios of the right triangle are:
