Answer:
The last one
Step-by-step explanation:
The 2πrh bit calculates the area of the rectangle at the middle by multipling its height (h) and its width (2πr which is also the circumference of the top and bottom circles) the second 2πr² bit is the areas of the two circles which both have areas πr² so when you have two its πr²+πr² which is 2πr²
