Answer:

The answer is<em><u> V≈197.92cm³</u></em>

Step-by-step explanation:

Remember that the radius and the height must be in the same units - convert them if necessary.

The resulting volume will be in those cubic units. So if the height and radius are both in centimeters, then the volume will be in cubic centimeters.

The volume of a cylinder is found by multiplying the area of its top or base by its height and is defined as: V = π· r2· h

Example:<em> A cylindrical water storage tank has an inside base radius of 7m and depth of 11 m. Find the capacity of the tank in kiloliters (1kl = 1m3). </em>

<em>Solution: </em>

<em>Base radius: r = 7 m </em>

<em>Height: h = 11 m </em>

<em>The water storage tank is in the shape of the cylinder. So using the volume of cylinder formula we can find the volume of it. </em>

<em> </em>

<em>V = π· r2· h </em>

<em>V = π· 72· 11 </em>

<em>V = 1692.46 m3 = 1692.46 kl</em>

Yes, you can divide $5 by 2. There are 100 cense in a dollar, 500 in five dollars, if you divide 500 by 2 you get 250 cense, with each 100 cense equaling $1. You would have $2.50.

Also, you got number 5 wrong, it’s how far he’s gone, not how far he has left.

How can you write 1,360/200 as a repeating decimal?
Alisiya [41]
1360/200

13.6/2

6.8

It is a finite decimal, but if you want repeating, there are zeroes that follow, like so:

6.8000000000000 . . . (and on to infinity)

What is the domain of the function
Ksenya-84 [330]

Answer:

x\geq -6

Step-by-step explanation:

The domain of a function is all of the values that x can be under that specific function. In this case, we're asking what values of x allow \sqrt{\frac{1}{3} x+2} to exist.

In order for square roots to exist, the quantity under the square root must be greater than or equal to 0, because you can't take the square root of a negative number. Therefore, we can write the following inequality to solve for x:

\frac{1}{3}x+2\geq 0

Solving this inequality, we get:

\frac{1}{3}x+2\geq 0

\frac{1}{3}x\geq -2 (Subtract 2 from both sides of the inequality to isolate x)

x\geq -6 (Multiply both sides of the inequality by 3 to get rid of x's coefficient)

Hope this helps!

Please help me :). I'll give brainiest
Dennis_Churaev [7]

Answer:

axis of symmetry: x=3, vertex: (3,23)

Step-by-step explanation:

-\frac{b}{2a}=-\frac{12}{-4}=3

axis of symmetry(x-value of the vertex): x=3

input this value into the function to get the vertex

-2(3)^{2}+12(3)+5

-18+36+5

18+5

23 is the y-value of the vertex

(3,23)

plz mark me brainliest. :)
