A cylinder has a radius of 14 m and a height of 7 m. What is the approximate surface area of the cylinder? Use 3.14 for π. A. 1846 m2 B. 3617 m2 C. 7235 m2 D. 9847 m2

OpenStudy (anonymous):

????????????????

OpenStudy (anonymous):

okay hold on

OpenStudy (anonymous):

ok

OpenStudy (anonymous):

A≈1847.26m²

OpenStudy (anonymous):

So if you are looking for the approximate estimation (Which you are) then the answer would be A

OpenStudy (anonymous):

ARE YOU LOOKING FOR THE PERIMETER?

@Ummah.Naja

OpenStudy (anonymous):

Im still here. just trying to get the answer

OpenStudy (anonymous):

Okay I know that the; Surface area= 232 m2 and the Volume= 224 m3

OpenStudy (anonymous):

And 232-224=8

OpenStudy (anonymous):

And that \[232\div224\]

OpenStudy (anonymous):

=1.035714285714286

OpenStudy (anonymous):

So if you round that you would get D.

OpenStudy (anonymous):

D

OpenStudy (anonymous):

I believe that might be your answer. I am not totally sure

OpenStudy (anonymous):

ok

OpenStudy (anonymous):

let me know if it was wrong
