To calculate the surface area of the coffee can (which is a cylinder), we can use the formula given:
\[ SA = 2\pi r^2 + 2\pi rh \]
Where:
- \( r \) is the radius of the base of the cylinder,
- \( h \) is the height of the cylinder.
You'll need to provide the values for the radius \( r \) and height \( h \) of the coffee can. Without the specific dimensions, I can't perform the calculation. Please provide those values, and I can help you calculate the surface area!
