Answer 1

Answer:

question 5 = 167.5ft^3 so yeah correct

question 6 = the 4th answer = 2388ft^3

Volume  using full pi = ; 2389.2ft^3 or 2389 ft^3 to 4sf.

Step-by-step explanation:

question 6 =

We have 13 Diameter. Which is 6.5 radius

D = 13

R = 6.5

H = 18

Surface area a of cylinder pi x 6.5^2 =  132.73229

or 42.25pi

Then we just multiply by the height to get the volume.

42.25x 18 = 760.18 pi

or 132.73229 x 18 =2389.18122

Volume = 2389.2ft^3 or 2389 ft^3 to 4sf.

As the answer given is 2388ft^3 then show your pi workings as 3.14 or 3.1459

Answer:

40 mph

Step-by-step explanation:

s = d/t

a to b's distance = 180 miles

7:30 - 12pm = 4.5 hours (time)

speed = 180 ÷ 4.5

speed = 40

40mph because it is 180 miles away and it took him 4.5 hours u divide 180 by 4,5

Find the values of x and y that make each quadrilateral a parallelogram. Show your work.

Answers

Step-by-step explanation:

A. to make the quadrilateral a parallelogram, we have:

7y + 5 = 8y - 4

112 = 10x - 8

<=> y = 5 + 4

120 = 10x

<=> x = 12

y = 9

B.we have:

17 = 4x + 5

63 = 8y - 1

<=> 12 = 4x

64 = 8y

<=> x = 3

y = 8

How do you solve this?

Answers

Not sure if you wanted answers or explanation on what to do. Ill just do the explanation and if you want the answers just lmk C:

R=1/2 d, and C=pi*2r. So you basically take the given number and plug it into these formulas.

Answer:

21. D = 5.67(rounded to the hundredths)

R = 2.84(rounded to the hundredths)

22. D = 13.4

C = 42.08(rounded to the hundredths)

23. C = 33.28(rounded to the hundredths)

R = 5.3

24. D = 1

R = 1.57 or pi/2

Step-by-step explanation:

Formula: C/pi = D

D = 2r

pi = 3.14

21. D = 17.8/3.14 = 5.67(rounded to the hundredths)

R = 5.67/2 = 2.84(rounded to the hundredths)

22. D = 6.7*2 = 13.4

C = 13.4 * 3.14 = 42.08 (rounded to the hundredths)

23. C = 10.6 * 3.14 = 33.28(rounded to the hundredths)

R = 10.6/2 = 5.3

24. D = 3.14/3.14 = 1

R = 3.14/2 = 1.57 or pi/2
