Question

The radius of a cylinder is 3.5 ft. The height is 14 ft. Find the surface area and volume of the cylinder to the nearest tenth of a foot.

I think the volume is 538.51 in^3.

I just don't know the SA. Is it, possibly, 164.85 in^2. Or, no where closer than that answer?

Answer 1

For the volume I got 538.8 ft^3 to the nearest tenth of a foot.
(you should really use a better value for π than 3.14, most calculators have it built in correct to 10 decimals)

Your SA is made up of 2 circles + a rectangle
SA = 2π(3.5)^2 + 2π(3.5) = 384.8 ft^2

Answer 2

IM RIGHT



Given:
radius : 3.5 ft
height : 14 ft

Surface Area of a cylinder = 2πrh + 2πr²
S.A. = 2 * 3.14 * 3.5ft * 14ft + 2 * 3.14 * (3.5ft)²
S.A. = 307.72ft² + 2 * 3.14 12.25ft²
S.A. = 307.72ft² + 76.93ft²
S.A. = 384.65 ft²  

Volume of a cylinder = πr²h
V = 3.14 * (3.5ft)² * 14ft
V = 3.14 * 12.25ft² * 14ft
V = 538.51 ft³

Answer 13

bruh no answer?

Answer 14

guys do the work yourselves

Answer 15

WHAT IS THE ANSWER!!!!!

Answer 16

I just need a SIMPLE version of the formula to I can do the math with out getting a headache. That literally all I want.

Answer 17

You guys are no scope 360 Smolbrain moment

Answer 18

This website is not just to give u answers it’s about helping you understand.

Answer 19

Pls just explain the problem

Answer 20

Given:
radius : 3.5 ft
height : 14 ft

Surface Area of a cylinder = 2πrh + 2πr²
S.A. = 2 * 3.14 * 3.5ft * 14ft + 2 * 3.14 * (3.5ft)²
S.A. = 307.72ft² + 2 * 3.14 12.25ft²
S.A. = 307.72ft² + 76.93ft²
S.A. = 384.65 ft²

Volume of a cylinder = πr²h
V = 3.14 * (3.5ft)² * 14ft
V = 3.14 * 12.25ft² * 14ft
V = 538.51 ft³

I hope this helps it took me a bit to get this but try to change it up a bit

Answer 21

Stop spamming, it annoys me.

Answer 22

The top people tell the answer, but use a formula from you lesson!
*flaps wings nervously*

Answer 23

ok the dude tha said i hope this helps on the bottom is a freakingc copy and paster the dude above gave it and now he cpoied and pasted it bruh u gotta stop

Answer 24

wait @Science Test Pls Help, why are you on a math quiz?

Answer 25

U-U ya know you've got a point there ╮(╯-╰)╭ @Science Test Pls Help why u here.... (⊙_⊙)？

Answer 26

also i will post my answer (that i did on my OWN and not some brainy copy and paste) after i finish :D

Answer 27

ok this is kinda hard but i have the answers
the surface area of
the cylinder is
384.85 and the
volume is 528.51

Answer 28

it has not been graded yet so sry is its not right

Answer 29

guys just solve this its easy then you get your answer.

A=2(3.14 x 3.5 x 14) + 2(3.15 x 3.5^2)

Answer 30

dudes the answer is on the top of this page
and also i agree with everyone too stop the spammers

Answer 31

I know the answer but all you guys wanna do is spam so figure it out yourself

Answer 32

Answer 34

meow its 2022 and we arent idiots lets help each other

Answer 35

So what's the answer I need to check mine I know mine's completely wrong I need serious help with this.

Answer 36

2πrh+2πr2=2·π·3.5·14+2·π·3.52≈384.8451ft²

Answer 37

it’s not funny what’s the flipping answer guys

Answer 38

IM RIGHT

Given:
radius : 3.5 ft
height : 14 ft

Surface Area of a cylinder = 2πrh + 2πr²
S.A. = 2 * 3.14 * 3.5ft * 14ft + 2 * 3.14 * (3.5ft)²
S.A. = 307.72ft² + 2 * 3.14 12.25ft²
S.A. = 307.72ft² + 76.93ft²
S.A. = 384.65 ft²

Volume of a cylinder = πr²h
V = 3.14 * (3.5ft)² * 14ft
V = 3.14 * 12.25ft² * 14ft
V = 538.51 ft³

Answer 39

for Mystical's answers what does the 12.15 mean

Answer 40

Area simplified
2x3.14x3.5x14=307.72
12.25x3.14x2=76.93
307.72x76.93=384.65
Volume simplified
3.5x2=12.25
12.25x3.14x14=538.51

Answer 41

Sorry
307.72+76.93=384.65

Answer 42

this is chaos lmao-

Answer 43

Hi,:/ give me answer or i use frost breath.

Answer 44

help

Answer 45

;-;

Answer 46

I ate chicken sandwich

Answer 47

I can simplify the answer to volume, but I'm having trouble with the surface area still. Sorry!
Since the formula for volume is V=𝜋r^2h, the formula for this problem would be: V = (3.14)(3.5)^2 (14)
This would equal 538.51, which rounds to 539 ft.^3.
Hope I could help!
