B is the answer I chose but there are the steps so you can see how to solve it
Answer:
Part a) The lateral area is 
Part b) The area of the two bases together is 
Part c) The surface area is 
Step-by-step explanation:
we know that
The surface area of a right cylinder is equal to

where
LA is the lateral area
B is the area of the base of cylinder
we have


Part a) Find the lateral area
The lateral area is equal to

substitute the values


Part b) Find the area of the two bases together
The area of the base B is equal to

so
the area of the two bases together is

Part c) Find the surface area of the cylinder

we have


substitute
