Question

V = π*r 2 *h

V=π*(16) 2 *24=19301.9inches^ 3

　

S.A.=2*π*r 2 +2*π*r*h

= (2)(pi)(16)(16) + (2)(pi)(16)(24) =

1280πinches^ 2 =

4021.2inches^ 2

Answer 1

someone help me do this but it not good can someone look it over for me

this is the comment i got for it from my Instructor

In general, we can use the superscript which is in the editor by the Greek character (such as x²)
or you can use ^ such as x^2 to indicate raising to a power.

For the area you are correct in that we will use (PI)(r^2)(h) to compute the volume.
The height is 24 inches as you noted. But the radius is not 16.

For the surface area, it looks like you are using the correct formula, but again, the radius will not be 16.

Answer 2

\(\text{Volume}_{\text{Cylinder}} = 2 \pi r^2 h\)
It's r^2 not r*2

But otherwise yes you're good :-) And ty for remembering the units!

Answer 3

good job! ^_^

Answer 4

thank you so that all i need to change in it after that everything is good :)

Answer 5

or u can just remember that a cylinder is a circle with h

Answer 6

so formula would be V=Ah

Answer 7

and area is area of circle

Answer 8

but she said it not 16

Answer 9

I'm still lost with this

Answer 10

where is the original question

Answer 11

your instructor says everything is fine except the radius. you may be using diameter in place of radius. check once

Answer 12

This is what I had the frist time

Answer 13

MODELING - Complementary Angles The difference between the measures of two complementary angles is 16°. Determine the measures of the two angles.

x+y=90 x-y=

16 add them: 2x =

106 x =

53 Get y: y =

90-53 =

37

They are 37 degrees and 53 degrees

Answer 14

ok

Answer 15

is that good

Answer 16

thats correct. how this is related to volume question ?

Answer 17

sorry post thr rong one

Answer 18

V = π*r 2 *h

V=π*(16) 2 *24=19301.9inches^ 3

　

S.A.=2*π*r 2 +2*π*r*h

= (2)(pi)(16)(16) + (2)(pi)(16)(24) =

1280πinches^ 2 =

4021.2inches^ 2

Answer 19

this is the solution you worked out. where is the question ?

Answer 20

r = 6 inches in the attachment
you're using r=16 wrongly

Answer 21

thats the mistake in radius your instructor is talking about :)

Answer 22

ok

Answer 23

In Exercises 7–16, determine (a) the volume and (b) the surface area of the three-dimensional figure. When appropriate, use the key on your calculator and round your answer to the nearest hundredth

Answer 24

that is the question that come with it

Answer 25

it have the pi in it after use the

Answer 26

replace 16 with 6 in your work. you will be fine

Answer 27

ok

Answer 28

you have put r=16 in your work
replace it to r = 6

:)

Answer 29

thank you so much

Answer 30

no problem :D

Answer 31

so it would look like this

V = π*r 2 *h V=π*(6) 2 *24=19301.9inches^ 3 　 S.A.=2*π*r 2 +2*π*r*h = (2)(pi)(6)(6) + (2)(pi)(6)(24) = 1280πinches^ 2 = 4021.2inches^ 2

Answer 32

no you need to replace r and do the calculation again

Answer 33

replace r with 6

Answer 34

im sorry im just bad at this

Answer 35

V = π*r^2 *h

V=π*(6)^2 *24=2714.3 inches^ 3

　

S.A.=2*π*r^2 +2*π*r*h

= (2)(pi)(6)(6) + (2)(pi)(6)(24) =

1131.0 inches^ 2

Answer 36

hmm its okay for now. you should learn to use the formula atleast. its not that hard as it seems. pls try once. you can ask ppl here to teach you how to use formula, they will be very glad to teach you the formula rather than do the whole problem for you. hope you understand me :)

Answer 37

thank you and yes I will do that

Answer 38

okay :) all the best :DDD
