Does anyone actually help on here? Please do if you can

I think it's 453pi

Mehek (mehek14):

It's not 453pi Formula = \[2 \pi rh+ 2 \pi r^2\] Plug in 3 for r and 14 for h \[2 \pi * 3 * 14 + 2 \pi* 3^2\]

OpenStudy (pleasehelp2346788):

I got 320.442450666

Mehek (mehek14):

Don't multiply pi because that's in the answer

OpenStudy (pleasehelp2346788):

Okay so just add and multiply the other numbers?

Mehek (mehek14):

Yes

OpenStudy (pleasehelp2346788):

Okay I got 378

Mehek (mehek14):

How o.0 \[2*3*14+2*3^2=102\] Don't know how you got 378 :/

OpenStudy (pleasehelp2346788):

Oh I didn't add the 2 because I got confused

OpenStudy (pleasehelp2346788):

Sorry -.- so , do I multiply pi by the answer?

Mehek (mehek14):

Leave pi with the answer we just got \[102 \pi\]

OpenStudy (pleasehelp2346788):

Oh, that made a lot more sense... Thank you!

Mehek (mehek14):

You're welcome :)
