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?

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
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
Thanks Mystical

@BRO ok now this is big brain lul

100% 5head
what???????? I don't understand anything yall just threw at me :(((
and @k take a chill pill
So what is the answer?
What the answer I'm confusion-
I’m confused I need help

bruh no answer?
guys do the work yourselves
WHAT IS THE ANSWER!!!!!
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.
You guys are no scope 360 Smolbrain moment
This website is not just to give u answers it’s about helping you understand.
Pls just explain the problem
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
Stop spamming, it annoys me.
The top people tell the answer, but use a formula from you lesson!
*flaps wings nervously*
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
wait @Science Test Pls Help, why are you on a math quiz?
U-U ya know you've got a point there ╮(╯-╰)╭ @Science Test Pls Help why u here.... (⊙_⊙)？
also i will post my answer (that i did on my OWN and not some brainy copy and paste) after i finish :D
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
it has not been graded yet so sry is its not right
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)
dudes the answer is on the top of this page
and also i agree with everyone too stop the spammers
I know the answer but all you guys wanna do is spam so figure it out yourself
@IsabellaDuran is right if all you guys wanna do is spam why should she tell you guys 😂
dummies that's not what I am lookin' for I am supposed to be lookin' for thee volume, idiots
meow its 2022 and we arent idiots lets help each other
So what's the answer I need to check mine I know mine's completely wrong I need serious help with this.
2πrh+2πr2=2·π·3.5·14+2·π·3.52≈384.8451ft²
it’s not funny what’s the flipping answer guys
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
for Mystical's answers what does the 12.15 mean
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
Sorry
307.72+76.93=384.65
this is chaos lmao-
Hi,:/ give me answer or i use frost breath.
help
;-;
I ate chicken sandwich
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!
