Question

PLEASE HELP IF YOU CANN :((((((((((((((((!!!!!!!!!!!!!!!!!!!I POSTED THIS OVER 24 HRS AGO AND STILL DIDN'T GET AN ANSWER.

Find the surface area of the cylinder. Give your answer to two decimal places. SHOW YOUR WORK so I can see if ur answer makes sense!

Answer 1

Surface area of the cylinder

`= 2\pi{r}^(2) + 2\pi{r}h`

`= 2\pi {8}^(2) + 2\pi(8)(15)`

`= 128\pi + 240\pi`

`= 368\pi`

`= 368× 3.14`

`= 1155.52`

Answer 2

Surface area of cylinder is: 2пrh+2пr^2

So (2*п*8*15)+(2*п*r^2)

Which equals 368п
