Question

Find the surface area of the cylinder in terms of pi

Answer 1

\[surface.area =2 \pi r^2+ 2 \pi rh\]

Answer 2

the diameter is 17
so r = 8.5

Answer 3

h= 13
solve everything except pi

Answer 4

yes but when I did that before I got some really huge number that doesn't fit with any of the choices...what do you mean except pi?

Answer 5

hmm
\[A= 2 \pi (r^2+rh)\]

Answer 6

I still got a number to big with the one above

Answer 7

okay i will tell the final answer

Answer 8

what are the options

Answer 9

but @aajugdar please tell me how you got your answer cause I have more questions like this and I want to know how to do it as well..

365.5 cm^2
799 cm^2
586.5cm^2
1,020cm^2

Answer 14

each has the pi up in the corner before cm btw @aajugdar

Answer 15

okay lets see now
i got 365.5pi cm^2

Answer 16

okay

Answer 17

\[A= 2 \pi r ( r+h)\]
\[A= 2 \pi *8.5(8.5+13)\]
\[A=2 \pi *8.5(21.5)\]

Answer 18

\[2 \pi (182.75) = 365.5 \pi cm^2\]

Answer 19

Okay thanks!
