If r = 5 units and x = 7 units, then what is the total surface area of the cylinder shown above?

A. https://media.studyisland.com/cgi-bin/mimetex.cgi?225\pi\,\text{square%20units}

B. https://media.studyisland.com/cgi-bin/mimetex.cgi?120\pi\,\text{square%20units}

C.
https://media.studyisland.com/cgi-bin/mimetex.cgi?95\pi\,\text{square%20units}

D. https://media.studyisland.com/cgi-bin/mimetex.cgi?350\pi\,\text{square%20units}

Answer 1

I say the answer is B @sunnnystrong

Answer 2

Recall that the total surface area of a cylinder is:
\[TSA_{cylinder}=2\pi r^2+2\pi r h \]

Answer 3

@Tate_Langdon .. is there a picture of the cylinder?

Answer 6

Ahhh... okay so
If you have some cylinder where h=7 & r=5
than-->

\[TSA_{cylinder}=2\pi (5)^2+2\pi (5) (7) \]
\[TSA_{cylinder}=376.99units^2 \]
