r =  d/2  =   6/2  = 3

 

SA  = 2pi r  ( r  + h)  =  2pi * 3   ( 3 + 8)   =  66 pi  in^2  ≈   207.345 in^2

Hey there!

 

The rule for the suface area of a cylinder is:

 

\(SA=2\pi r^2+dh\)

 

Knowing this we can just plug the numbers into this:

 

\(SA=(2\times \pi \times 3^2)+(6\times 8)=...inches^2\)

 

Let me know how you go :)
