Answer:

$192\pi \: {cm}^{3}$

Step-by-step explanation:

h = 12 cm, r = 4 cm

$V_{cylinder} = \pi {r}^{2} h \\ = \pi \times {4}^{2} \times 12 \\ = \pi \times 16 \times 12 \\ V_{cylinder}= 192\pi \: {cm}^{3}$

Answer:

Step-by-step explanation:

18 - 2^4 * (-0.5)

Calculate 2 to the power of 4 and get 16.

18−16(−0.5)

Multiply 16 and −0.5 to get −8.

18−(−8)

The opposite of −8 is 8.

18+8

Add 18 and 8 to get 26.

PLEASE I NEED HELP QUICKLY!!! Find the solution for the given system of equations in the form (x,y).

goblinko [34]

Answer:

(4, - 4)

Step-by-step explanation:

Given system:

-x + y = 8
7x + 3y = - 16

Multiply the first equation by 7 and add up the equations:

-7x + 7y + 7x + 3y = 7*8 - 16
10y = 40
y = 4

Find y:

-x + 4 = 8
-x = 4
x = - 4

Use the dchnition of similarity to solve the following problem.

sveta [45]

Answer:

1063 ft

Step-by-step explanation:

For shadow problems, we assume the sun's rays are parallel, so the triangles formed are similar. That means the ratio of height to shadow length is the same for each object.

h/(580 ft) = (5.5 ft)/(3 ft)

h = (5.5 ft)(580/3) ≈ 1063 ft

The height of the monument is about 1063 feet.

An amusement park has discovered that the brace that provides stability to the ferris

antiseptic1488 [7]

Answer:

Hence the correct answer is option (A) 4.708.

Step-by-step explanation:

Solution:-

Now, we need to find the angle of the sector by using sector formula,

$A = 28.25 ft^{2} \\r = 12ft.\\\\28.25 = \frac{\theta}{360^{o} } \times \pi \times 12^{2} \\\\\theta=\frac{28.25\times 360}{12 \times12 \times \pi} \\\\\theta =( \frac{70.625}{\\pi} )^{o}$

We now convert the angle to radian

$\theta = \frac{70.625}{\pi} \times \frac{\pi}{180}\\\\\theta = 0.39236 radian$

Now we calculate the length of arc by arc formula

$\theta=\frac{I}{12} \\\\0.39236 =\frac{I}{12}\\\\I = 4.708 feet.$

So, The length of steel that must be replaced is 4.708 ft.
