Find the Volume of the composite figure below.
olya-2409 [2.1K]

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...

25 pts to who ever can help with this question:
pentagon [3]

Answer:

A. 5s+2

B. 8s+8

C. 75

D. 27

Step-by-step explanation:

Is difficult to read the exact expressions. If a mistake is present then fix the number and use the same method.

A. The perimeter of the square is all 4 equal sides added together. The length of a side is \frac{5s+2}{4}. Since there are four sides then:

P= \frac{5s+2}{4}+\frac{5s+2}{4}+\frac{5s+2}{4}+\frac{5s+2}{4} = 5s+2

Adding 1/4+1/4+1/4+1/4=1. This applies here leaving 5s+2 as the answer.

B. The perimeter of the rectangle is all four sides added together. A rectangle has two pairs of equal side so P = 2l+2w.

P = 2(s+9) + 2(3s-5)\\P = 2s+18 +6s-10\\P=8s+8

C. If s=5 then the sum of the two perimeters is:

5s+2+8s+8

5(5)+2+8(5)+8

25+2+40+8

75

D. Subtract the two perimeters by computing s=7:

8s+8 -(5s+2)

8s+8-5s-2

8(7)+8-5(7)-2

56+8-35-2

64-35-2

29-2

Proper
vlabodo [156]

Answer:

  QR(3), RS(3), PQ(3), ST(11), RP(6), RT(14), SP(9), QT(17)

Step-by-step explanation:

The diagram is not shown, but we assume the points are in the sequence ...

  P, Q, R, S, T

Since QR = RS, R is apparently the midpoint of QS, So ...

23. QR = 6/2 = 3

24. RS = QR = 3

25. PQ = QR = 3

26. ST = PT -PQ -QS = 20 -3 -6 = 11

27. RP = PQ +QR = 3 +3 = 6

28. RT = RS +ST = 3 +11 = 14

29. SP = PQ +QS = 3 +6 = 9

30. QT = QS +ST = 6 +11 = 17
