Answer 2

Answer:

4πrh + 2πr²

Step-by-step explanation:

Let the radius of the cylinder = r and height of the cylinder = h.

Given that it is placed over the other cylinder.

Then, the height of the new cylinder = 2h.

∴ Total surface area of the cylinder = 2πrh + 2πr²

                                                           = 2πr(2h) + 2πr²

                                                           = 4πrh + 2πr²

∴ Total surface area of the shape formed = 4πrh + 2πr².

Hope it helps!
