Answer:
A. 2(Pi)rh+2(Pi)r^2
Step-by-step explanation:
The surface area of a cylinder is the sum of the lateral area and the area of the two circular ends.
The lateral area is the product of the circumference of the cylinder and its height:
lateral area = 2πrh
The area of the two ends is twice the area of each of those circles, so is ...
total end area = 2(πr²)
Then the total surface area of a cylinder is ...
SA = 2πrh +2πr²
