Answer:

564.512 m³

Step-by-step explanation:

Formula to find the volume of a cone is :

Volume = \frac{1}{3} π r² h

Here,

r = radius = 7 m

h =  height = 11 m

Let us solve now.

Volume = \frac{1}{3} π r² h

Volume = \frac{1}{3} π ×7² × 11

Volume = \frac{1}{3} π × 49 × 11

Volume = \frac{1}{3} π × 539

Volume = \frac{1}{3} × 1693.538

Volume = 564.512 m³

Hope this helps you :-)

Answer:

V = 564.2 m^3

Step-by-step explanation:

The volume of a cone is given by

V = 1/3 pi r^2 h  where r is the radius and h is the height

V = 1/3 pi (7)^2 (11)

V =539 /3 * pi

Letting pi be approximated by 3.14

V = 564.1533333 m^3

Rounding to the nearest tenth

V = 564.2 m^3

68% of the tickets sold at a water park were child tickets. If the park sold 50 tickets in all, how many child tickets did it se
Mnenie [13.5K]

Answer:

\boxed{\bf\: The  \: park  \: sold  \boxed{ 34{}} \: child  \: tickets.}

Step-by-step explanation:

<u>Given:</u>

Percentage of Tickets sold at a water park - 68%

The Number of Tickets if the park sold in all - 50

<u>To </u><u>Find:</u>

The Number of child tickets the park sold.

<u>Solution:</u>

We know that 68% equals to 68/100.

Step 1: Multiply 68/100 by 50 which is the number of tickets the park sold :-

\sf \:  =  \:  \cfrac{68}{100}  \times 50

<u>Note</u>:The Simplified form of 68/100 * 50 would be the answer to this question.

Step 2: <u>Cancel One zero of 50 and one zero of 100,That is</u>:-

\sf =  \cfrac{68}{ 10\cancel0}  \times 5 \cancel0

<em>Results to,</em>

\sf  = \cfrac{68}{10}  \times 5

Step 3: <u>Cancel 5 and 10, That is</u>:-

\sf  = \cfrac{68}{ \cancel{10 }}  \times  \cancel5

<em>Results to,</em>

\sf =\:  \cfrac{68}{2}  \times 1

\sf = \cfrac{68}{2}

Step 4: <u>Cancel 68 and 2, That is</u>:-

\sf =\:  \cfrac{ \cancel{68}}{ \cancel2}

<em>Results to,</em>

\sf  =  \cfrac{34}{1}

\sf  = 34

34 is the result.

Hence,

\underline{ \rm \: The  \: park  \: sold  \: \bold{ 34 } \: child  \: tickets.}

Find the axis of symmetry of 2x^2 + 12x + 16 Show your work
raketka [301]

The vertex form:

y=a(x-h)^2+k\\\\(h,\ k)-vertex

The axis of symetry is x = h.

y=ax^2+bx+c\to h=\dfrac{-b}{2a}

We have

y=2x^2+12x+16\to a=2,\ b=12,\ c=16

Substitute:

h=\dfrac{-12}{(2)(2)}=\dfrac{-12}{4}=-3

<h3>Answer: x = -3</h3>
