Answer:

<h2>972 pi ft^3</h2>

solution,

Volume of this composite figure

= Volume of cylinder+volume of cone

Formula to find volume of cylinder:

\pi \:  {r}^{2} h

Formula to find volume of cone:

\frac{1}{3} \pi {r}^{2} h

Use,

\pi =  \: pi

Here,

Radius of cone= radius of cylinder

=9 ft

Height of cylinder=10 ft

Height of cone=16 ft-10 ft=6 ft

Nowz

Volume of the figure:

\: pi \:  {r}^{2} h +  \frac{1}{3}  \: pi \:  {r}^{2} h \\  =  \: pi \times  {(9)}^{2}  \times 10 +  \frac{1}{3}  \times  \: pi \times  {(9)}^{2}  \times 6 \\  =  \: pi \:  \times 81 \times 10 +  \frac{1}{3}  \times 21 \times 6 \times  \: pi \\  = 810 \: pi + 162 \: pi \\  = 972 \: pi \:  {ft}^{2}

Hope this helps...

Good luck on your assignment...

Given that,

Total fuel = 200000 L

Used fuel = 130,000 L

We need to find the percentage of the used fuel. It can be given by :

\%=\dfrac{130,000}{200000}\times 100\\\\=65\%

So, the required percentage is 65%.

Kwans The Kenningy account balance was $20 his ending balance is zero dollars what integer represents the changing in his accoun
77julia77 [94]

The integer number that represents the changing in his account balance from beginning to end is of -20.

<h3>Which numbers belong to the set of integer numbers?</h3>

Non-decimal numbers, either positive or negative numbers, also zero, belong to the set, which can be represented by:

Z = {..., -3, -2, -1, 0, 1, 2, 3, ...}

A change can be represented by the <u>final value subtracted by the initial value</u>. For this problem, we have that:

  • The initial balance is of $20.
  • The final balance is of $0.

Hence the change in the balance is:

0 - 20 = -20.

And the integer is -20.

PLEASE HELP ME ASAP SOMEONE
Eduardwww [97]

Answer:

E (3,-1)   D (-2, -2)   G (-1, 3)    F (3, 2)

Step-by-step explanation:

90 degrees = (y, -x)

that means you take the ordered pair you want to rotate and plug the x and y into the new spots.  

for example, point E is at (1,3) so the point rotated 90 degrees is (3,-1)
