Answer:

Step-by-step explanation:

1.  Find the circumference of the cylinder:  C = 2πr

2.  Multiply this result by the height of the cylinder:  A = 2πr·h

3.  To this result add the surface areas (there are two) of the ends of the cylinder:  2πrh + 2πr²

This is the correct general formula for the surface area of a cylinder of  radius r and height h.  If you want specific numbers, please share the values of r and h.
